It is impossible now to access Bitcointalk with TOR

At least for DDoS by attacker who use Tor network, it can be mitigated by enabling PoW feature.

Only for onion service though. Forum would have to have a onion version and Tor users have to surf using that only.

In general, for the clearnet version, CloudFlare would still be a necessity. For VPN users, CloudFlare challenge probably wouldn't be too much of a difficulty for them. They aren't abused as badly, but I'm not sure if CloudFlare specifically labels them (I know they do for Tor). Saw your quote as well, I guess we wouldn't be shifting away from CloudFlare any time soon.

That's true. I simply mentioned it since CloudFlare already support alt-svc, where currently Tor Browser user actually visit .onion when they access this forum.

How demanding is it to make an onion version of the forum? Considering that these attacks last longer and longer, it would be really good to have an onion version that, if I understood correctly, would be resistant to such attacks.

Onion version of the forum can only guarantee anonymity but will still be venerable of DDoS attack to an extent.
Again, I don't think that theymos will buy the idea because of the reputation of the forum. Having an onion version might take the government's eyes to the forum and some kind of legal compliances would be required.
Besides, running an onion version of the forum will require some more resources to reconfigure the server and secure same against attacks. I don't think we are committed to all these now.

Not very. Onion sites are vulnerable to DDOS in a similar fashion by exhausting its resources.

It is not illegal, to my knowledge for sites to host onion mirrors. Generally, most of the prominent websites that does this does not have to comply with any additional regulations. In fact, if a government sanctions them for doing so, then I would think it'll be a red flag for the forum.

It wouldn't be as difficult, after all you'll just be running a mirror that serves content over Tor. My impression previously was that they didn't have a good way to rate limit and restrict certain identities. I recall this being mentioned a long time ago, but please CMIIW.

CF does it better over clearnet, albeit being a big PITA for Tor users with captchas. As mentioned, CF can already serve content within Tor (alt-svc mentioned by ABCbits) which is why there isn't usually captchas until the site gets attacked.

If PoW with Tor works, I think having a dedicated onion site without CloudFlare but with PoW would be a possibility.

I don't know it will help or not but you may try the Tor settings that I have shared in one of my threads. I used Tor to visit the forum when it was having severe issues and that time it helped me to browse the forum.

I thought to make a post to help others too and this is the thread I created where I showed the steps with which Tor worked for me.

You may try those settings mentioned in that thread and who knows it might solve your issue.

You mean the same government agencies that also have their own onion versions? If we go in that direction, maybe Tor and VPN should be banned due to the reputation of the forum - only then would we lose at least 50% of members overnight... because in some (for the forum) important countries this forum is banned.

So that I don't seem like I'm talking nonsense, here's a link to an interesting onion site -> Link
