Im not an IT guy, but i still dont see a connection, other then that the is from brasil. Is his IP in that list?
And what does a guid with 100 means? Does that mean he is admin on every server ?
I think it's the highest PBPower value you can have, which makes you kinda invisible player admin.
fact #1:
server admins, check out the following file, located at your system/pb folder of aa2:
pbpower.dat
this entry will be appended to this file, you will be surprised:
[06.03.2016 18:00:22] 100 7695df6c0524a57e511e2f720f56db46 "?"
the value of 100 will give to this GUID high power on your server (which you maybe dont want)!! If you try to delete this, it will be appended again by assist.
and another surprise! guess who is in line with this GUID (Global User ID)?
we check now:

I can verify this, I found the very same file from both IGC and BIG servers with 78 rows of same command, giving pb power for same GUID, I don't know for whom it belongs but Im sure Merlin has it right over there.
Im curious as well why on earth this PB Power thing was done, my guess is it's connected to the drama we had when Pit got booted, guess Possessed wanted to make sure if he sees him online he can deal with him straight away?

Also like Placid said nothing there seems to be connected to any person, so maybe these are two different cases: PB Power - gate and DDoS attacks
