I have about 100 messages in my MySpace inbox from users asking questions about apps. I reply to a few at a time, but I am worries that if I reply to too many, I may be flagged as a spammer. Is this correct or is it safe to reply to as many people as message me?

 You'll only get tagged for spam, if the user reports you as spam. If they are asking you questions, and you respond.. then there should not be an issue.
