The original message sent to you informing you of your latest suspension includes the information about the reason for the suspension. I cannot make this public. I do recommend that you re-read that original message, and contemplate your current course of action.
As to your question: having many posts flagged would not itself warrant a suspension. Otherwise some rogue group of users could start flagging every post by, say, Brian M. Scott causing him to be suspended. Even having numerous flags on your posts judged to be "helpful" would not itself warrant a suspension. Posts are occasionally flagged to become Community Wiki, for example, which, while helpful certainly shouldn't cause the owner of the flagged post to be suspended.
But a history helpful flags indicating to the moderators consistent behaviour which is not tolerated would give the moderators cause to look and see if a suspension is warranted. Let me be clear
the behaviour is the reason for the suspension, not the flags.
