Hi Art247,
The things which stand out for me as a quick brain storm are:
1. Do not send out excessive personal messages with making contact with people you don't know... as this will lead to spam complaints...
2. Attempting to make too many friends/links with people you dont know... again leading to complaints...
3. Spam postings on other peoples walls, posts/articles etc
4. Do you best to provide value with participating in discussions and not commenting for the sake of doing so (as with forums in general)... In addition this applies to when reaching out to groups to which you wish to join.. Again be helpful and participate positively as otherwise they will complain...
If its not to do with Internet Marketing and to do with reputation, family safety, privacy etc... then check out:
