I don’t know if anyone uses the TOR network to access the forum, but if you do you may never see this message.
Unfortunately the forum (like many other forums across the world) is suffering from a dictionary attack trying to guess your forum password. The idiots running the attack are directing it through the TOR network so all the IP addresses are spoofed (anonymous). As the attack shows no signs of abating I’ve taken the decision to block all TOR router addresses from the server. This unfortunately means that any legitimate TOR network user will also be blocked. Luckily I don’t think there are many (if any) people affected by this. The TOR IP addresses I’ve seen so far haven’t been used by any forum users.
