Seriously this. This has happened for years and it's so frustrating. If you type over 150 characters the site thinks you're spam, if you format (double enter/enter) you're spam, if you link you're spam. Nothing ever gets unflagged. In fact this reply will probably be marked spam and automatically deleted. There has never been an answer or reply in 10 years as to why this happens or how to fix it. Once you get marked spam it seems impossible to fix it and get a post through on a mod.
