Experience: Little to none.
Why is everyone overreacting? I mean, I know that this happens a lot, and I know that it is against the rules. But though he does have over 100 posts, he is still pretty new. I mean, just report him, he gets and warning, and be done with it. There isn't a reason to be mean to someone who doesn't know the rules. Tell him what he did wrong in stead of just telling him he did something wrong.
So, what you did was post more then one suggestion per topic (wishlist) which is against the rules. It is also against the rules to post a megathread. It is also vague. You are also asking for suggestions from other people. Just try not to do this in the future.
