Maybe because he said that it had 33 SATK at Lv100?
Which could very well have been a typo. You don't just say somethings hacked because a very low stat has been posted.
If someone posts about a level 100 pokemon, and they say its got a stat value below 100, the first duty of a hack checker in this thread would be to ask if they're 100% sure that they've posted the correct stats.
Then after they confirm that they've posted the right stats, then you can make calls on legitness.
Also look at the below;
HP- 263 attk- 175 def-197 sp attk- 33 sp-def-193 speed-278
Notice how shes posted her stats all over the place. With some theres a space before the actual stat value(but with most there aren't). Surely its entirely plausible to assume shes made a typo whilst entering the values, and the actual S.Atk stat was 133, and even if it wasn't, its up to those who actually post responses in this thread to ask if the OP is sure of the stats, before telling them its hacked, especially with such a daft stat like 33 S.Atk on a level 100 Darkrai.
With the kind of attitude that people have in here, in regards to calling pokemon hacked/legit, Its no wonder theres so many hacks out there, and why so many in this thread have been getting rid of possibly legit pokemon, because those answering if its legit, don't take the time to realise there might be something amiss with what the OP may have posted.

None of that was aimed at you SOW.
Its just that all of the above statements i made, seem prudent to do, in a thread that deals with hack checking.
