Actually, I was wrong.

The original ban was my friend. He was on an alt trolling in servers.
The second was my brother, who aimbots also but that is besides the point. They may have been botting/playing together judging by the time margin between bans.
I was the latter, 16 hours after them. I simply connected to the server on the same Wi-Fi after they got banned by SMAC, and I received the same punishment.

There were seven accounts banned while connected to that IP because it is a public network...my school's to be more precise. It is the "Staff" internet though (to be honest the password is simple), I can sort out the cheaters that I know of from the rest.

http://steamcommunity.com/id/lightningboltnigga/ -- The original's alt (BOT)
http://steamcommunity.com/id/samjaws04/ -- The originals friend ... I believe the original uses this account from time to time, but as far as I know its clean (CLEAN/BOT?)
http://steamcommunity.com/id/anthony123459/ -- " " (CLEAN/BOT?)

The last three are friends of the original, which makes sense as to why they'd also know the Staff Wi-Fi password, but I am not certain that they use an aim assist as well. If Skial records STVs on their servers you could probably tell.
I am also "the originals friend" but I do not bot, nor do I endorse aimbots. If any solid proof is required I'd be happy to supply it, whether it supports all of my claims or just relieves me of my ban (ex. a POV from one of my competitive matches/scrims) by showing that I do not cheat.
