He is probably talking about the recent thread that got deleted because of the extreme spam that was coming from the campaign.
Joining a signature campaign and making constructive posts in the whole forum it's ok. Paying users to do insubstantial posts in their threads is already against rules, but it was even worse considering that the campaign from Decentraland was allowing users to do 10 posts per day in the same thread.
Here is theymos answer:
That is very much
not allowed. The threads are trashed, the poster is banned for 60 days, everyone who participated is banned for 3 days, and everyone who participated cannot display a signature for 30 days.
You and the poster above you are the only ones who actually read the title. These other people can't read. The title says "pay to spam" which means as it says being paid to spam. Nowhere does it suggest spamming in any campaign then people post their reply and tho a few lines about the wrong thing.
Anyway if you have to ask then you already know the answer. Ignoring the fact that the form doesn't allow it, it is a horrible thing to do. Esspecially if they want you to spam negative comments or try take down other coins or invade their threads. Just imagine the utter choas that would cause ? Noone will be another to post anything without being stacked by spammers. It would basically run the forum. It can happen. I have seen and expierenced online games becoming unplayable because of hackers and the same will happen here except instead of hackers they spammers. You shouldn't even be entertaining this notion and I'm not sure why you are. Let it die please.
