I am getting very tired of seeing people put up stupid pkmn with nothing special about them and asking for shinies, and legends, and even shiny legends for them. Seriously, you want to trade, say, a regular bunnelby that you caught off of the very first route and you ask for a Mew. I just saw one where someone put up a regular zubat and wants a shiny lapras.
If you want a shiny pkmn then offer something worth that shiny. Offer another shiny you have, or maybe a flawless pkmn, or a HA pkmn as long as the shiny you want is gonna be regular. If you want a shiny flawless pkmn then offer something worth it. Don't offer a regular pkmn that anyone can catch.
I don't find that reasonable. If you don't have much to trade, then try to do it yourself or try breeding something for someone. Go into the friend safari and catch some HA pkmn to trade for the pkmn you want. You may actually find a shiny while you're hunting for the HA pkmn. I have.
You can even offer up items for them, as long as the items are reasonable, too. Dont say you'll give a pokeball to someone for a shiny or anything. Earn some BP and get the battle items and trade them off, as long as you don't need them.
I know that not a lot of people have good luck with shinies or have the patience for breeding, but don't offer up something that isn't worth what you're asking for. And if your pkmn is hacked or cloned and you want a legitimate pkmn then you should tell that person it's cloned or hacked in any way, b/c that person may not feel that it's a fair trade, and then if they found out the pkmn you traded is cloned or hacked and you failed to tell them that then they can report you, and then you get a lovely PM from one of the mods saying you were reported and you get in trouble.
Just please. Stop making trades like that. It's not a fair trade, and some people are gonna automatically assume you're trolling everyone, and that's just gonna make people mad and not want to trade with you at all.
