-blam!-ing hate the pokemon community

Seriously I have had 4 pokemon stolen from me and I feel like smashing my DS because of it. How the -blam!- can people seem to think that getting traded a pokemon that needs traded to evolve suddenly = I can keep it. I have lost a Alakazam, Machamp, Spritzee evolution and a gigalith. All I want to do is fill my pokedex and yet I got these -blam!-ers stealing my pokemon. I refuse to trade anything that requires an item to be held at the same time or something I cannot get in the wild. Has this happened to you? Or are you one of the -blam!-ers that steal them? I think I have only had 1 guy trade back n forth with me to evolve our pokemon turns out he was a rare person.
