Flood Check is a feature on ROBLOX which prevents Copy and Paste spams and bots. If you post a comment, you will have to wait a while (approx. 60 seconds) before you can post another comment. If you try to post a comment when you have flood check on the forums, it will show this message: "You are posting too fast. The flood check has blocked your post. Please press back and try again in a few seconds." If you post comments too fast on other places like on a game, it will show this message in your text box instead: "You are posting comments too fast. Wait a while until your next comment."
