Hi,
If some user left the telegram, admin can not remove he/she from group.
the user last seen long time ago.
after remove, telegram do not remove and do not show any message.
@omoridi Is it possible to remove them in https://web.telegram.org?
I heard this: "You can't remove deleted user from your group, you only can wait for some time (~1 week) and this user should disappear"
@john-preston @DaFri-Nochiterov That does not happen, actually can not delete these "ghost" users. The same on Android. In support they told me that only can be done directly with iOS Telegram 馃槗. I have seen some users disappear, but after a long, long time.
@haevalencia Is it possible to remove them in https://web.telegram.org?
@john-preston
It's not possible. Luckily I could find a user with these property since Telegram web only shows the last 50 users connected to the group. I tried it in Chrome and Firefox on Windows 10.

Method: channels.kickFromChannel
Url: N/A
Result: {"_":"rpc_error","error_code":400,"error_message":"USER_ID_INVALID"}

@john-preston I've tried using TDesktop and Webogram and may delete users with deleted accounts. I think it was a bug server side.
Cheers
@diazbastian may or may not?
@auchri api issue? :)
@stek29 Currently is possible to expel users with deleted accounts.
Tested:
Telegram Desktop 0.9.47 alpha and webogram stable
Yeah, in Webogram does not throw any errors :+1:
This ticket can be closed, telegram desktop now can kick deleted accounts.
