To get right to the point, this is a violation...period. Posting adds, hyping or pumping a stock should be flagged, and put an explaination that the post is SPAM.
Agora will delete it and ban the user if the HL's continue to report it.
What is important here, is many people read and do not post. Clutering up the main discussion forum with OT posts and SPAM makes it difficult for everyone to wade through the posts in search of substance. It is the duty of all posters, not just HL's, to keep the forum ON TOPIC.
My 2 cents, DISCHINO.
