Hate to say this - but you lot look like a bunch of farmed accounts.. all with a similar structure username, all with that silly altcoin under your avatar space and all span up within a month of each other.
I am no forensic guy, but it looks odd to me - maybe some others will comment about it.
As pointed out by TMAN, I also think that these account must be linked with each other as there are too much similarities between their username pattern, posts and personal text. Why these same looking accounts are posting on a same thread ? Is this coincident or something else ? I am not sure but still have doubts.
