Why use TOR at the first place anyway? Can't you use normally? I never used TOR. So I never faced anything like that.
People use TOR for various concerns to their privacy, anonymity, security against bugging and you can't question their wisdom in doing so.
Sometimes I would get random time outs or verification failed but not that you got.
The random time outs are common to all forum members using a normal browser like chrome, except for a newbie that might be experiencing it for the first time will get worried over it.
