Hi @Urbanecm,
I'd like to offer a few insights from an admin's point of view about the viability of the change filter. I'm writing new filters for these types of edits & account creation. It usually can block some types of vandals, but for these two I couldn't found a sustainable solution with filter. Even if I can find patterns sometimes to block them, it won't work because of the automatic disable of editfilter actions when the filter has higher match rate from usual. While they are active, they are exceeding the rates, so community discussed about reducing the rate of anonymous edits per minute as a solution.
If you have another suggestion, which will work, I can translate & ask to the community.

Hi,
It caught my attention that users without autoreview rights can still use ContentTranslation. Could you check & fix it?
