Maybe ask them to block your account? That would keep them from seeing anything you talk about, though it'd also block any other communication here if that's a problem.
This isn't particularly noteworthy or concerning, imo. These two communities are probably the least likely to care about authenticity, and also best suited for a system that's only real success is spinning moderately coherent fictions. They have and will always be most interested in drama, which is easy to fabricate.
The real danger of these systems is shaping public discourse by sheer volume of noise. They can make any opinion seem overwhelmingly supported, or tear apart opposition with distractions and infighting. And they do it with a single-minded focus spread across thousands of voices.
All of those comments and posts will remain on instances they have federated to. Transferring posting history would necessitate resubmitting every single post you've ever made, needlessly and messily duplicating one user's presence across the fediverse. And in the case of a closing instance, that bulk is multiplied several hundred or thousand times over. Not a reasonable request by any stretch.
One of my only gripes with the instance was it's refusal to defederate yours, and y'all over here celebrating the closure after the admins took that stance really just affirms how wrong that decision was.
Looking forward to moving to an instance that is free from your shittiness. 👋
Ah yes, the halceon days of non-stop pop-up ads and malware taskbars. /s
Not to mention that everything they mentioned was absolutely started to become what it is today. Nothing changed, they just progressed their plans over 20 years. Pretending it was all started with benevolent intentions is naive at best.
