First, I never mined / traded USDE or PXL.
2. I don't own the address 1NoH3uohKp6s2HShTVFc8VfayNLWkvy9Sm.
3, I guess my bitcointalk account was hacked, I guess someone got in and traded with you guys and scammed you.
4., sorry I should have been using a stronger password on bttalk, my bad, but wasn't an easy one.
5. You should have been using an escrow service.
6. I'll be trying to trace back the hacker to see if I can find any information about him.
7. Let's keep an eye on 1NoH3uohKp6s2HShTVFc8VfayNLWkvy9Sm we'll eventually see where the coin's flow to and we may track the fucking scammer.
8. I'll check back all the pms.

Updated
* This morning, I've seen that I was logged off from btttalk, so yes basically someone other just logged in my account.
* I guess he's the one that ignored you. I've unblocked you guys.
* I see a suspect message here: https://bitcointalk.org/index.php?topic=420571.msg4570263#msg4570263 - I've never sent this personally.

Again, I'm personally not the fucking idiot that scammed you, my bitcointalk account was hacked. Though I'm willing to take any actions needed to track the bastard and help you guys to get your money back.

Is there a feature for bitcointalk that can show logged in IP's history?

I'm not blaming you, but it's your fault for not using an escrow service and my fault for getting hacked. I'm trying to help you out. But it's your take. Go name&shame if you like to in which I'll stop offering my help (which I've already pm'ed admins to get the ip log) -- and good luck getting your BTC's then..

Again, my account was hacked, someone got in my account and scammed you. I can prove this once i got the ip history if admins send it to me. I'm a pool operator and really don't need your 0.4 BTC. I do have a reputation around and not willing to destroy it for your 0.4 BTC.

But I was unlucky & careless which eventually lead to my bitcointalk account being hacked (as you know bitcointalk has been hacked quite a few times, I guess someone got my password meanwhile).

You either go with me and I'll try my best to find the actual scammer and try to get back your 0.4 BTC or just name & shame which you'll be on your own -- then I can just say is good luck getting your BTC's back.

If I was an actual scammer, believe me I wouldn't be spending my valuable time for your fucking 0.4 BTC, but would be stealing instead the amount our pools have distributed to our miners which worth 88.849 BTC up to the moment ( http://www.coinium.org/poolmanager/stats/overall ).

please go create the topic now instead of waiting 22 hours. you are already trying to ruin my reputation with sending messages after all of my messages on forum. again i didn't steal your  btc's  and i was trying to help you guys out.

but you're just blaming and not listening, and just shaming. go on please, if you think you can get your btc's by just ruining my repu just go on.

still i'm sorry you guys got scammed but I'm not the one personally that have done this - i don't need 0.4 BTC and my forum reputation/coinium.org pools worth far more than 0.4btc x2.

if i was a scammer i wouldn't be posting all my personal information on this account with all my linkedin and github links within my signatures. so basically this account is traceable, you can check my github, linkedin and stuff.

i'm really not dumb enough to scam people with a reputable account that has github/linkedin links easily accessible. better then that i'm not a scammer.

if you still believe i'm a scammer, you got my information available -- if you really believe that I scammed you, i've the information available so you guys can track me -- if this all sounds correct.

in fact 'raistlinthewiz' is a really good account to hack if you are a scammer. the account is pool operator's, reputable, has personal information available. In last few day i've noticed a few disconnects from bitcointalk.org when i opened the page, but thought it was cookie stuff that was messed or somehow bitcointalk was having difficulties.

But i understand then that, I'm hacked, somebody logged in to my account using my password, didn't change it, just used it to scam people and deleted the pm's and post's he used.

Believe it or not but this is the truth. Put yourself here, would you scamming people with a reputable account that had links to stuff that's bound to your real-life information? I guess you wouldn't. Which I wouldn't be doing so.

I suspect that my account password was same with my freenode irc password, and I guess I somehow sent nick identification message to some public channel by mistake and somebody got the password from there to use the account.

another possibility is that as you know bitcointalk was hacked a few weeks ago with man-in-the-middle account, they may have been captured my password during that..

Again i'm sorry to hear that you guy's got scammed, but the case is you just got scammed and I was HACKED.

STOP blaming me for trusted you!!!
