Who is deleting non-harmful team forums?

lichess.org/forum/team-mystery-land-20/rules-and-regulations
Gone.
What is happening?
Who deletes this?

@mysterious_1 It is Harmless not non-Harmful

Ok Ok thank you for correcting me @DebayanRay

Team leaders can do that.

@risky-chess they can only close it, right?

Yeah @mysterious_1

Only Team Leaders can close.

There is also a possibility to delete individual messages.But I think this is not the case here,as the topic was closed.It says "Page not found"

Yeah, same with another forum in the team,I was editing a post and boom!forum is gone

@mysterious_1 @risky-chess as a team leader you can delete all forum posts - when there is no one left the thread disappears exactly like that picture (Page not found)
