Any account that suddenly woke up after last being active in 2017 (specifically that year, because if I'm not mistaken there was a hack or a mass selling of accounts) should raise eyebrows.  I've caught a lot of accounts that changed hands from that era, and I think I tagged many of them a while back.

The end of 2017 was when a lot of shitposting members who'd been in those lousy ICO bounties took off after the crash, so even if an account hack or sale has nothing to do with someone waking up, I suspect they're coming back for a reason--and that reason would be to start making money again somehow. 

Are bounties even still a thing anymore?  I haven't checked the bounty subsection of the altcoin board in a while, so I don't know what's going on with them these days.  In any case, EtihadBitcoin deserves to have a set of eyes focused on him by anyone concerned with forum post quality or account sales or what have you.  There might not be anything malicious going on (yet), but this does raise a red flag for me.  Then again, I'm about as paranoid as a bitcointalk member can get.
