Hmm... It all depends. Perhaps we need 2 different LOL buttons.
1. LOL-AYBS
2. LOL-YSF
Where #1: LOL At You Being Stupid and #2: LOL-Your So Funny!
Actually, only #2 should be used. But it should be defined that the LOL is a LOL-YSF, not a LOL-AYBS.
The real issue here is that the forum's code would need to be modified in order to add code that would modify the database in order to track the LOLs in the same way it does Likes and Thanks. We're talking Database Modifications and Code Modifications that would take someone quite familiar with the code of the forum's software to be able to pull it off. Then there are the legal issues. Is the forum software used an Open Source? Does it have a license that allows it to be modified and changed? Does the request have to go through the developers of the forum software in order to have the changes made, and, if so, will these developers need to be paid a large sum of money to get it done?
Tapatalk can't do it. They only implement an interface to the existing forum software, and, unfortunately, while LOL would be a good idea for all forums, there aren't any that I know of that do it currently. Not that there aren't, I just haven't seen them yet. That means it would be a pretty obscure feature. But, at one time, Like and Thanks were both pretty obscure. It could happen.
