Hi ​@Casper_B, we can't answer this question here at the community hub but you can file a ticket - appeal:

https://support.strava.com/hc/en-us/requests/new?ticket_form_id=37255043127181

Problem is he can't appeal, because there is no case number, because there was no notification of a ban or a suspension

Oh - this should create a ticket too. But I see that the case# is a mandatory field in that form, which makes it a catch-22-ish kind of loop… so perhaps first switch the form type from “Appeals” to “Login and Account Access”, that should allow creation of a ticket without actually already having a ticket, and only then continue with the appeal..?

Yes, done that already :). Any idea if something like this is normally resolved? I guess it is against the ToS but it was quite innocent really. If anything, a (permanent) ban seems a bit harsh. Especially without notifying the banned person. Isnt it stravas policy to notify someone when banning them?

Have they looked to make sure a notification wasn’t sent to their spam/junk folder?  

Yes already checked, nothing at all
