As a person who actually sold his "legit" diamond account through this website. I would completely be cautious dealing with this guy.. Here is what was said through skype and his skype name is dennis.oh1. He also deleted/blocked me after this conversation so beware.
[2:03:11 PM] William Russell: Hey; did you add me? My skype was weird on my phone
[2:04:45 PM] Dennis Oh: yeah
[2:04:50 PM] Dennis Oh: Whats up
[2:04:56 PM] William Russell: nothing much man, you?
[2:05:11 PM] William Russell: Which account is it?
[2:06:21 PM] Dennis Oh: It's a triple dia acc
[2:06:30 PM] Dennis Oh: atm season 3 rating is 2k
[2:06:41 PM] Dennis Oh: Some guy offered me $2200 for it though
[2:06:44 PM] Dennis Oh: double dia* sorry
[2:06:59 PM] Dennis Oh: Just waiting for his payment, if he backs out though, you can offer me
[2:07:08 PM] William Russell: lol well you would be insane not to sell it as it's no where near worth that
[2:07:16 PM] William Russell: what's the name of the account?
[2:07:18 PM] Dennis Oh: Yeah
[2:07:19 PM] William Russell: I was 2397
[2:07:22 PM] Dennis Oh: I'm going to sell it to him lol
[2:07:33 PM] William Russell: what's the summoner name?
[2:08:52 PM] William Russell: ?
[2:09:07 PM] Dennis Oh: Don't feel comfortable giving it out since you aren't buying it anyway lol
[2:09:19 PM] Dennis Oh: If the other guy backs out, then we can talk again
[2:09:40 PM] William Russell: lol so you're saying your full of **** because giving out the name doesn't do anything
[2:10:00 PM] Dennis Oh: kk think what you'd like lol
[2:10:04 PM] Dennis Oh: I don't really care
[2:10:16 PM] William Russell: lol ok i will let epic npc know as I am reputable through them

[2:10:29 PM] Dennis Oh: kk

I was a 2397 diamond player and sold that account here so I would know pretty much all the diamond players.. He wouldn't give me the summoner name of the account so there was no way to confirm this. If you actually want to purchase this account pm the summoner name and I can easily confirm for you in game as I know pretty much all the 2.2k+ players.
I'm selling lol account too (not for that much) but i wont share my summoner name either until $ received, it's nothing unusual.. but ofc there is alot of risk for that kind of cash.
