I really dont remember names.Could you name few? If it related to the ru-ua war and if they popular I'm pretty sure I might know them.
Also you should don't mix up banning by TG team during moderation, and for example deleting one when police arrested owner of the channel, got access to it and delete it/restrict or channel removes automatically due to inactivity.
I am aware of the distinctions between banning/moderation and deleting. Specifically the apple issue is very clear as I use both apple and android. The moment I cannot find the group or channel anymore on apple and android is deletion for me.
Where accounts have been deleted which managed a channel or group you are right with saying that a message pops up that its scheduled for deletion. At the same time I see some of those groups/channels being present long after they are allegedly scheduled for deletion.
TG -for me- is just a nightmare from the beginning. Its for sure not private by default and I think that a lot of people are misled by that (on purpose?) and that its now out of control for the collective governments, hence the attacks on TG / free speech.
