Also, I don't know why I forgot to mention this, but recently we had a member create a simple script that allowed went through and could like/dislike every single post in the forum in a relatively short period of time, regardless of whether they had access to the board or anything else.
Script and explanation can be found here:

Do you know of anyway to prevent such scripts from being used to abuse the system?
