who would have thought pissing people off has negative side effects...

like people reporting you to valve...
people reporting you to your ISP...
and getting banned from servers...

As for this thread, it was a poor attempt at trolling.

OP got lamed for not reading the valve TOS/Subscriber Agreement and was corrected by DougV (using the classic "the link is not hard to find" style).

As for the ban reason (spamming music) [KM], Valve and even your ISP has every right to shut you down.

[KM]:
- Spamming / Trouble making
- Uploading copyrighted content to our servers for distribution by [KM]

Valve:
- Pissing other players off
- Distributing copyrighted content via their services

Your ISP:
- Breaking "online services" rules & TOS
- Uploading copyrighted material to a remote IP

Notice the pattern here?

Welcome to the internet - where people can be shut down just as in "real life".
