I never trade for exp because it could always be botted, so looking for the general trade flow, nobody should trade for exp because it can be botted so exp has no value on trades??
This is definitely true, you should be taking caution with EXP. Although, this last event showed that just trading Pokemon worth a lot can be bad as well, a lot of Rotom (Pokedex) were caught by bots and thus removed. Any deal should be done with caution.
