I understand that mods cannot be around all the time, and that some members feel the need to "test" the rules or to attempt to spam threads or posts, due to certain issues with members and posts I wish to recommend if possible a system to issue a limit or delay to the number of threads that can be created by a user within a certain length of time and also the number of posts they can make consecutively within a period of time so that the forum does not get flooded by multiple posts from the same user.
If possible also to make sure that this does not annoy the basic users that understand how things work, would it be possible to issue this limit as a warning / response to a situation like this instead of 'nerfing' the entire community?
Also on a small side note I think there should be a limit to the signature size as it can be distracting for some of the regular forum users to have to look at an image that is ridiculous in its scale.
