Well accusing is a different thing, but to me atleast this whole thing smells miles away. They also took the rule of 100 characters per post away, so you could basically wear the signature, and write a bot which spams the whole forum with nonsense bullshit.
My god, you don't stop once you start do you?
First off, the rule was at least 100 words per post, which was kinda nonsensical considering their pay-rate and if you have a look at any "good" campaign. Glad they removed it
The rates are the lowest which i have seen, basically could be considered as (slave work).
Another one of those posts where people feel entitled to get a "job-level" payrate in BTC for posting with a sig. Its an incentive people, it started with a scammer named Tradefortress and for some reason every other BTC service continues to invest in it thinking it'll improve their visibility.
TheAlso they failed and paid out users two payments for one week, so i doubt that such exchange can even be trusted, because they cannot even handle a simple bitcoin transaction. Now imagine if that happened with customer funds. "OOPS! We just paid everyone's withdrawal 2x times", they would definetly not make up to that as they don't even have money for decent budget.
Payments for this campaign are done manually as opposed to automatic payments in an exchange. I don't even see why this is seen as a bad thing that they paid out twice the amount they were supposed to.
As long as Nexybit pays, I don't think that you can accuse them of being "scammers". But it certainly makes the unprofessional considering they are essentially explicitly employing spammers as their promotional medium which will not end well for themselves.
This sums up the situation, what they're doing is not scamming, many sigs have escrowed themselves and it was up to the users to trust that they'd be paid(and most did) and its not all spammers who join the low-paying camps. For example I'm joining just so I can have a decent post history so that I can be accepted in any future campaigns, and the low rate is just something on top.
