Just so you know, you covered the EV part of the Mandibuzz you posted, but we can see its IVs and Stats = It's easy to tell the EV spread on it...

293177 Uhm is it ok? My reason was for others not to copy it , and im thinking that its my right , please throw some insights :) thanks ppl

If you're selling a pokemon, and blurring the ev spread, I assume you've got something to hide. For example, maybe you messed the evs up considerably, and if I buy that pokemon, I'm going to have to pay a lot more to fix those evs. That is something you should consider when posting pokemon: Perception of others. Sure, it could indeed be your right, but what are the buyers going to assume about that pokemon they are thinking of buying?

As long as you can see the stats, you may know the ev spread anyways.

You can do, however if someone asks you should show them whether it be on the forum post or via pm in response to their query. Players need to know what they are buying, if EV spread is a mess this can affect what people are willing to pay, if they are perfectly EV trained this also can affect what people are willing to pay, afterall not a lot of people like to bid-blind.
