This user is only newbie in rank, but he is registered over a year ago. Also, if you look at his post history, since reactivating, he's mostly trying to promote his YouTube channel.
Yeah, and he doesn't exactly remind me of anyone else in particular--though there have certainly been newbie accounts that have. The most recent and obvious examples of that would be TOAA/cryptohunter and the various other alts he's employed.
I get what OP is saying and I think sometimes it's true, sometimes not, but usually it's really hard to tell unless there are glaringly similar styles of writing between accounts. Since a lot of members here write in mediocre-to-poor English, I have a hard time connecting accounts based on that.
And it usually doesn't matter anyway. If I see a good post, I'll merit it. In fact, if it's from a newbie account there's probably a greater chance that I will, as I like helping newbies rank up.
