Yes you are probably right.
So showing the moves could go along with a link to
en.wikipedia.org/wiki/Threefold_repetition maybe?

Your topic however inspired another idea to prevent reoccurring topics especially in the Q&A.
Probably there is a reason for lichess not telling a player right away when he got caught cheating. But they'll figure out anyway once they address the community with their "issue", since someone will tell em.
So why not instead of allowing a flagged player to ask a question in the Q&A right away, just show them a "in between screen" like this:
Dear User,
the answer to your question with a probability of over 99% is that you have used some sort of assistance during your games on Lichess.
That is why you are not allowed to participate in tourneys anymore and the lobby looks kind of empty at times.
However if you did not use any kind of assistance during your games you should write an email to contact@lichess.org.
If your question was totally unrelated and you still want to address the community click here and solve another chess captcha. =)
Maybe it could also check if the user did participate in the forum and/or Q&A prior this. If not it is most likely he wants to report a "not able to play" bug.
I think it would be nice getting rid of this sad daily topics. They just have a paranoia supporting effect on the community and I would not mind reading them any more.
Kind of watching news 24/7 and see the worlds problems all the time, instead of the nice things.
