Honestly reminds me of the days that these websites would have filters for specific words or combination of words and it was so hilariously busted. People that wanted to get specific words across just....would bypass the filter, and others that didn't realize there was a filter would find themselves with a warning or the ilk.
And your options are limited when it comes to reports. I've been on places where reports do nothing and also the same time where reports just blanket ban the account even if the reports are all fake.
