There is a user who has joined nearly every Strava Club. with very few exceptions everyone of his rides is recorded on a supposed Turbo Trainer, with no supporting evidence that he has completed the activity claimed. no link to Zwift or similar. 

He claims rides and distances that are simply not credible. recently he recorded two rides in one morning, for which there were simply insufficient hours to manage it.

I have raised with Strava admin. who simply ignore the problem, other than to suggest his rides be flagged. 

Any suggestions as to how to deal with such a cheat?
