No, not at all - we're completely independent. If you really want DDR, go play DDR!
Those were handled by Chris, who really doesn't have time for the project anymore.
If you didn't do anything ban-worthy one of the admins may have hit the wrong button when cleaning up spam. Accidents happen, if it was your only post then you should make a new account (you can use the same name). Otherwise, let us know in #stepmania-devs on irc.freenode.net and we can restore your account.
There might be. We're interested in doing it once we've got a new stable release of the game and the new site is capable of hosting the files.
We don't currently host any, but you can find a bunch in the forums!
Our thanks. Donations are mostly used for developer hardware expenses and sometimes helping pay the bills. We don't make any money from the site itself or the game, so they really mean a lot.
StepMania is designed to run on arcade cabinets and it is within your rights to use it for a commercial game, but we do not endorse machines with unlicensed content being used for profit. We have nothing to do with the content that might be on these machines, but we do not police how people use it, nor do we believe everyone else should suffer for the abuses of a few people.
We absolutely support properly licensed games made with the StepMania engine though, such as Pulsen and (defunct) In The Groove, PIU PRO, etc.

Absolutely! You'll still need to mind which songs you play though, as we're not responsible for that stuff (other than the few included ones - which are all CC-NC, so you might not want to get ad revenue off those).

You're probably using a Variable Bitrate (VBR) MP3. Convert it to CBR MP3 or OGG (OGG is the best choice for StepMania, you should be using it) and the problem will go away.
