Are there spam filters to catch the abundance of spam that has been happening lately? They seem easily distinguishable. Blocking posts from low postcount people that have russian/etc letters and posts that have a title inside a thread would already get rid of 90%.

You can even do it like reddit does, put them on a blacklist which they aren't aware of. Their posts will only appear to themselves but are invisible to everyone else, so they can't catch on to being blacklisted so easily.
