I have a big problem, I have a technical blog with lots of visitors, comments are open so I get a lot of people that reach my site through Google and just leave comments that are basically just a bunch of smileys.
Today I tried searching for a bunch of combinations of random smileys inside the comment section of the control panel and ended up deleting around 3000 trash comments. So, my question is:
Is there a plugin that can help me detect that kind of comments (because tobe honest there must be hundreds of combinations of smileys)? also any other comment clean up plugin suggestion is very welcomed.
I seriously need to clean up my comments.
