just FYI (dunno if that deserves a topic and if this is a correct section), I wasn't active on this forum for a while, namely since 2017.
But during 2018 summer someone apparently hacked into my account and made several posts, you can see through them by viewing my message history. The hackers put some ads into my signature, I assume promoting these referral links was what they aimed to do. No private messages or scam attempts as far as I could see.
Some of the more strange parts was they wouldn't change my password or email and that's how I logged back into the account. Perhaps it was done in order to avoid triggering the forum script to send me a notification about password/email change.
The email wasn't compromised afaik and I can be somewhat sure about it as I have several things attached to it which are more valuable than my account here. I had a somewhat strong password and doubt it was obtained by brute-force attack. We all heard about bitcointalk database leaked (in fact I seen it for sale on several underground forums for few grands) and I would bet that was the case.
So the story is over. Honestly Im not bugged much about it, in fact they even managed to promote my account a bit haha
