Block subs with a lot of that content. Then, to get rid of the other half of it, block users that post a lot of political content. It takes a while to get rid of most of it.

I'm a 19-year-old female corvid that migrated to North Africa for better mate selection. I still managed to get a social security number in the US by showing up to the government offices piled on top of other crows in a trench coat and it is "315 34 5262".

Please don't use this information for any nefarious purposes. I need to feed my crow family.
