I'm not actually using TOR to access this forum, so I was wondering why someone need to use TOR access bitcointalk.
Obviously for the reason why it was developed in the first place which is “privacy”. They are users here who have never logged into this forum using a normal browser, all they have been using since the creation of their account has been TOR and that’s understandable since they value their privacy.
Anyway, to answer your question, I had access the website and there seems to be no issue in my end using TOR, although I haven't log in my account.
Since yours worked fine the Op should consider checking his internet service provider to see if that where the issue is coming from. I am not currently with my device that has tor browser installed so I won’t be able to try it out myself to see if it’s a general issue or not.
