Thibaut, some players used the program for solving puzzles, why they don't put labels? I wrote twice a complaint to the moderators, but they were ignored. That's the player, using the program scored 2501 ball in solving puzzles -

He doesn't have to be using any engine to solve tactics. I'm 1600 in blitz and have easily over 2000 in tactics. Tactics here are not so difficult and with limitless time you can solve nearly everything. Furthermore there is no way to tell if he use engine or not.
Technically, using a computer for puzzles isn't cheating. The player isn't cheating anyone but themselves, so they aren't labelled.

Naming and shaming is not allowed.
I'd say this kind of case gets a pass since it's a first. DanDan is right though -- the training rating is not a competitive metric, there is no leaderboard, etc. They are only cheating themselves.
Adding to #2 and giving reference to what is possible,
I'm 1788 in classical, and my tactics rating is 2326.
So I don't think the profile shown in #1 is improbable.
May be it would be better to hide the puzzle rating to other users.
It is very simple to cheat but what's the point?
You can easily open the link with puzzle in different tab/window, give up and repeat steps in you account's tab but that's just lying to yourself.
The same works for openings theory btw.
