It was impossible to access the forum with Tor for about 48 hours, I tried with various connection settings in Tor, but CF simply did not allow the captcha challenge to pass. Apparently the attack lasted a little longer than usual, but now everything is back to normal.
It's still not normal in my side. I am still using the VPN connection as I had no success from the TOR yet.
As reminder, using CloudFlare already reduce our privacy. I also recall theymos would change if there's other technology or service which isn't far more expensive than CloudFlare.
Privacy of the forum users comes first or the expense? If we did not have enough money than it was something else.
