I opened a thread a few days ago, and you can see how the sock accounts actually behave. Here I describe their behavior more specifically.
Adding long strings of Cyrillic letters, gibberish, and emojis into pages, comments, threads, and edit summaries.
Sometimes removing a large chunk of content.
I need the Abuse Filter to enforce our wiki rules more efficiently, such as prevent users from creating very short pages (only contains 1-2 sentence; this filter also exists in Wikipedia). I also want to port a few filters from Wikipedia.
I hope these pieces of information helps. Your help will be appreciated.
