SolvedScammers everywhere

So i've been banned from dayz for a few weeks, and decided
'hey, mpgh is a trusted site. I should have no problems buying a key and getting back into dayz if i buy from mpgh!'
How utterly wrong i was.
I bought 2 keys, off two different sellers. The first seller gave me a key that was in use, so i complained and he sent me another - which was in use too. I then bought off the second guy, who didn't email me the key. I informed him over skype and so he sent me a key - which seemed to be working. I played dayz for 20 minutes happily, and then went to the bathroom. When i came back, i opened arma 2 to play dayz again, and guess what? IN USE!
So i complained, and he gave me another - that was in use as soon as he sent it.

Now i have wasted £3 on keys, and i need 2 questions answered:

1: Why are most sellers on here absolute rubbish scammers?

2: Are there any actual, good sellers who will sell me a reliable key that will last atleast a week? If so, please name them so i can buy a frigging key.

Expect all $2-$5 keys (stolen keys) to go in-use once in a while.

If the key is in-use very often, then either the owner has no life, or the key seller (or his suppliers) have resold their keys.

Some key sellers retain keys that you complain are in-use (this is then sold to someone else when it's not in-use at a later point in time).

There are no reliable key sellers. Key sellers sell keys that are stolen. That means that even if you're lucky enough to buy a key from a primary source, there will at least be 1 other person sharing the key you bought.

From my own experience, I always try to get European or Asian keys (Asian keys work best), so the owner(s) that play on it will very likely play at a different time than I do.

KSnipz is a nice seller. Bought my first key from him and i did nothing wrong with it.

yeah...the in use problem is a very big problem..
actually most sellers cant do anything..the old owner get his key back and then uses again..
but u have to see the other point too that the sellers cant give you a longer warranty for in use keys cause like there are many seller-scammers out , there are as well customer scammers out who think they can fake a in use error and get some new free keys..or just hack aroung with the keys, get banned and then want a new free key and call the seller a scammer...

im trying to make my customers as happy as i can..but in some points you have to understand us too..

some ppl want too much of us..
they think they can buy for 2$ a key from us and play with it their whole life...BUT if it would be like this, then why the fuck we would sell them for 2$ if the original costs 15€?!?!

but everytime be careful where u buy..sometimes there are some good and cheap sellers but most of them(like subzerok) are obiviously scammers..

thanks for reading my opinion

@Bosegelucke . By far the best seller on here. Only person I would ever buy keys from. Vouch x100. However, keys are stolen. People get their keys back...sometime they download multiple "free hacks" from YouTube resulting in several sellers selling the same key...but that's why they're so cheap.

There is no honor among thieves.
