Hello @Medu5a,
Currently, those are the standards defined by the community and not made by staff members, there are no rules for this and there won't be any since everyone can have a different opinion on a value of a Pokemon.For you, it's 22+ or 25+, for some other, it's different.We cannot define for players such terms.
The only rule that exist regarding the stats is the 1st rule of our general trade rules that you can see here;
If you see an user breaking this rule then, you are free to report it by using our report center or our report button on forum.
So, regarding this :
As stated above,there is no rules regarding those terms so you can't report an user that do not break the rules.
I do hope that i have been clear, feel free to use our forum whenever you need :),
Wish you a good day,
Nyahoja.
