I was banned? It's me {A|B}BlasterMan

[blasterman]

So I figured I would return to play some TF2 for the new update and I thought, why not play on my old favorite server, UNF. So I tell my brother to join ( He is {A|B}Darkraider for those of you unaware), and he gets on fine, then I go to join and it says "You are banned from this server". After not playing for a couple of months, I am surprised that I was banned. Last time I played, there were no issues, and I haven't played since. Nobody has accessed my account and the ip isn't banned, just my account. I'm wondering who did this and why, and if anyone can help me out that would be great.

People I know/ remember:

Tide
Gentleman wearing old spice- an irl friend
December
Potato Skin
Bananahiefer- spelled that wrong I'm sure
Denca- SHARKS!
Retardicus
Frilly
Pauses- He was a beast
Specto- the snipa
Goblin
Some waffle dude
Lento
Insinic
Tributary
Ruffles- DUH
Prince of Hyrule
pgr2gamer
coltaine
suber
mr. e

And theres more that I cant remember but either way, I would like to be unbanned.

Don't know if anyone's even active anymore, but I can always hope...
