Are we going to take "nikjain422 was active on 6 AM and LamontFalkner was active on 8 PM" as solid proof? I don't think so.
More likely is that Glomerulus22 accidentally copied his alt account's ID "U=1277719"(nikjain422, preditor422) while investigating. But that is only assumption. *
Yahoo has also red trusted me saying I have cheated eroiy campaign but I have not. Instead of sending him the btc address through my account I accidentally sent him the address through my alt account. He red trusted me for that and I do not deserve it.
This is not so hard to prove.
I don't see any of these accounts here
https://bitcointalk.org/index.php?topic=3002004.0;all or here
https://bitcointalk.org/index.php?topic=3002007.0;all so looking at reference link, I figured there was another signature thread:
https://bitcointalk.org/index.php?topic=2827626.msg28977175#msg28977175Looking at that screenshot

predito422 was in Eroiy signature campaign while account
nikjain422 was in EBCOIN signature campaign.
PM "
do we have to apply again or we get in directly" indicates that someone who was already in Eroiy's campaign wants to know answer, and they probably logged in to wrong accounts.
So, question is - did both accounts enroll or have tried to enroll in campaign? My logic is telling me they figured that they sent PM from wrong account and then they sent identical PM from alt account only few minutes later.
