Please do not cooperate with them at all. Please do not send them anything.
You do not need these creeps and they are indeed creeps.
It’s very gentlemanly of you to try to treat people with respect by giving documents as they demanded but even if you give them what they demanded they will still attack you. No matter what you give them they will not stop attacking you. If you talk to them or send them anything then they will respond by attacking you more. Anything you say or do will prompt them to attack you more. The only thing that could possibly get them to stop attacking you is if you ignore them, don’t talk with them, and don’t send them anything. If you stop talking to them and don’t send them anything then sooner or later they will get tired of attacking you with the same insults over and over with nobody listening or caring anymore. But if you send them documents then they will attack you about the documents they send you because then that will be something new for them to attack about.
It’s best to just ignore them and not send them anything.
