I got the same PM, word for word.  It was probably addressed (and sent) to BountyDetective, then copied to anyone who left a red-tag.  It's hard to make out because he copied BountyDetective's post in the Alts Thread, but didn't use quote code.  Basically it's a bunch of rambling excuses and links to nothing that prove anything, and screenshots of nothing that prove anything. 

Anyway, I was looking for instances where the discord username "Ariful07#5546" appeared without the username "Ariful07" to put "reasonable doubt" to the test.  I only found the one instance, the same one quoted in the Alts Thread.  But that's not all, I found that Ariful07 and at least one of the alts are posting in the bounty threads in very close time intervals.

Here's one particular occurrence with mere 8-second gap:



And another example, a bounty application only 6 minutes apart:



There were others, and I don't care to post any more evidence.  I was looking for evidence indicating the tag is wrong, but now I'm convinced it's accurate.
