The major reason the addresses and the list of participants are in most cases public is simple. It's for the sake of accountability and transparency. Start encouraging hiding lists of participants and payouts, and you will breed fraud, corruption, and conspiracy theories.
I, for one, thought it was simply because that’s what everyone is used to.

Reporting could be made partially hidden - that is, without including the
BTC-addresses.
People need to see who has been picked to join the campaign, who has been removed, and who is receiving what.
That’s not the point; the goal is to hide only the
BTC-addresses. There’s no reason to hide any other information.
1. If you are uncomfortable with people knowing how much BTC you own from the signature campaigns, then move the funds to your unknown private address.
So that it’s easy to track on a blockexplorer?

2. Often use fresh addresses for different campaigns
Each of which is available in the spreadsheets for any sig.campaign (even those that ended many years ago).
3. Avoid participating in signature campaigns.
This is exactly why I like this forum. Whenever bring up a problem, someone is bound to offer a "brilliant" solution (instead of actually looking for the best one) along the lines of, "If you don't like it, don't use it".

4. It’s actually surprising that don't suggested using mixers or swaps. Those are all just "crutches" for a workaround, when the real solution could be much simpler.
Thank you for pointing out my mistake. The moderators have already moved the topic.
It's been brought up before, and it always comes down to this.
Anyone's free to make a private deal, and any campaign manager is free to change their system. It's a free market, and I don't think the forum should enforce anything in this area.
I never said that the forum itself should regulate this. The forum users need to arrive at some sort of "unwritten" standard (which the majority will accept voluntarily, because it is advantageous) that works for everyone (after all, the current standard for running sig.campaigns had to emerge somehow, didn't it?). This can't happen without discussion or, alternatively, it would have to be imposed by force by the campaign managers.
I see the point though, and it would have been a nice experiment to run a campaign with only
Silent payments, but I've never seen one. It just adds complications that so far nobody wants to deal with.
I, too, am coming to the conclusion that this is primarily a matter of additional complexities, rather than it being impossible to implement.
With all the data mining happening, let's not make it easy for prying eyes..this is a welcome move but for the sake of accountability, access to these spreadsheets can be extended to a few privileged users of the forum that can do their own investigations should something be off, otherwise welcome move!
Access for
BTC-community-respected users (auditors) to perform detection.
Start encouraging hiding lists of participants and payouts, and you will breed fraud, corruption, and conspiracy theories.
If one silently accepts the current state of affairs, nothing will ever change. That is why discussion is necessary - to at least attempt to find a good solution.
Btw how did the Sin*** payment address end up being blacklisted, was it not for the same reason such that payments for the last round didn't go to the campaign participants as those funds were hot 🔥and I believe exchanges monitor these addys to, and if not luck funds will be withheld.
Thanks for the tip, that thought hadn’t occurred to me. And, in fact, this could also create a problem for sig.campaign participants, if not now, then at some point in the future.
It's not a forum policy or a standard of signature campaign management but some managers have different management styles with some hidden information in their campaign spreadsheets.
No one is challenging (and heaven forbid anyone should try!

) a campaign manager’s right to independently develop their own approaches to managing sig.campaigns. I am simply calling for a discussion on this topic, one that includes the managers themselves, in the hope that some of them might take the arguments raised during the discussion to heart and decide to adjust their personal management approach.
This suggests that some campaign managers are, in fact, aware of the risks associated with publicly disclosing
BTC-addresses. Nevertheless, these campaign managers continue to follow the traditional application process, which requires users to provide their
BTC-addresses as part of their submission. Consequently, anyone interested can still find all these
BTC-addresses within the relevant discussion thread - even if they aren't consolidated into a single spreadsheet.
Alternatively, participants could provide one address when submitting their application, and then, upon acceptance, share a different
BTC-address directly with the manager; this second
BTC-address would then be the one actually used to receive rewards. How about this option? But this is on the condition that the spreadsheet is made inaccessible to the public (though other participants will still be able to see this information, won't they?).
It’s as simple as that, clearly separating your Hodl address from your signature campaigns address can prevent this without compromising the accountability and transparency involved in signature campaigns and this wouldn’t add any more workload to the campaign managers.
So,
the sheriff isn’t concerned with the Indian's problems?

I gather that most people hold the view that everyone should look after their own privacy.
What about all the alt accounts that got busted after sending their signature earnings to the same address

One could allow "detectives", users like @lovesmayfamilis to audit the hidden spreadsheets containing participant data, as they would likely continue their hunt for such alt accounts.
I wouldn’t assume that the established format for sig.campaigns and the application submission process were designed specifically to track down multi-account users and cheaters. It’s more likely that, when these sig. campaigns first emerged, the possibility of people creating alt accounts wasn’t even anticipated. It was only later that particularly cunning users realized they could use this as a way to earn some extra money.
If you're concerned about privacy then this is something you should speak to the campaign manager about.
You’re probably right. It’s the simplest approach and the one that requires the least effort from everyone for maintaining privacy. I’ve taken in everyone’s input, and now I have some things to reflect on.
Thank you all for your advice, recommendations, and the thoughts you’ve shared.
If I can remember correctly I think, this topic has actually been discussed before. Anyways the thing is you can't make the campaign payment process totally flawless privacy and transparency wise. Even if you don't make it public, the process is still flawed of address reuse.
Unfortunately, I didn’t see that discussion. Could you share a link? Perhaps I’ll find some other useful ideas there.
