I use a crummy little VPN to use blocked sites on campus as their blocked sites is really bizarre and have some websites blocked that I actually have to use to get some work done. My router I brought so I didn't have to VPN got confiscated like 2 weeks into classes and I cant get it back until the end of the semester if they even still have it lol. Normally I just disable it when playing games, but I forgot to once and it got me banned. Sucks lol, but iI will make sure to disable it so this never happens again.
I do not have any alts whatsoever, I do not believe anyone else uses TF2 on campus, and no one but me has ever used my account.
Right now my primary TF2 playing is done on a college campus, but I have had no problem with Panda servers with that connection.
On the off chance someone else on the campus plays on a Panda server and gets banned forever in the future I'll cut my loses there and just not play while on campus to make things simple, but no one has done that as I was fine until I got myself banned with the VPN.
