Normally we would prefer to address these types of issues outside of the main forum, but it may benefit others to see the answers too.
1. No, you have not been permenantly moderated. The usual way for this to happen is via infractions that accrue points, and none have been issued to you so far. You are just running into the same restrictions that all new members face. The moderation period involves both a period of time and a number of posts before it is over, and you seem to have exceeded both. Talk to an admin.
2. Does not sound normal to me. Try contacting an administrator (purehate, balding_parrot)
3. As for obscenity, we know it when we see it. Basically anything that looks like its posted by a bot or anything that appears to be advertising outside services - saying something like if I helped you then please contribute to my project would be an example. People here are menat to be volunteering their time, not doing it in return for favours.
4. I dont have any problem with you posting information about that here, just as long as it doesnt start to look like an ad.
