The only question is why they are ready to destroy their reputation for enough small(as for me) reward.
For someone even such sums costs more than reputation.
There are some people that are willing to compromise their reputation when they are really desperate for money. It's such a waste seeing those accounts being red-tagged because of supporting a scam when their accounts are already high ranked which is not easy to achieve. Those accounts could already be sold because if it's still handled by the real owner then he would know himself that it's not worth it to grab the offer of 1xbit.
That is a sad part, the accounts on the Hero / Legendary level stuck/Willingly promoting the campaign Hurts more then a Member / Full Member as Sr,Hero,Legendary Accounts with out any +Ve Green feedback considered as Trust worth and Natural. For sure as you said for some Bucks the people Desperate for money use to Ruin their reputation with such high rank which is a dream comes true for a Jr / Member.
Another point is that they are still promoting the campaign as they want grind as much money as much they can because now they cant turns all Reds into Neutral or Green.
I think that the most part of these account got their level before the merit system was created. Possible that they were bought from some bot farm. The main part of users that improved their accounts from the newbies for merit understand how much it costs and i don`t think they are willing to repeat this way.
I think that it doesn`t matter how they spend their rewards. They can even don`t gamble ever. The only question is why they are ready to destroy their reputation for enough small(as for me) reward.
But there are only 2 answers that i can imagine: someone even doesn`t cares about the company - they just make for what they are paid. And the second reason is money. For someone even such sums costs more than reputation.
For users living in third world countries, money is much more important than reputation "at least that's what I can imagine" so you will find some high ranking users no matter how bad their reputation is in promoting campaigns as long as they make money. Obviously their thinking is unwise so the decision will not benefit them in the long run considering no campaign will last forever on this forum regardless of how well known their brand is.
1xbit campaign participants are more likely to avoid playing on the sites they promote because they also know the reputation of the site is not good so they won't consider the risk of losing money, imo. It looks like participants receive payments directly into their btc wallet, so it's less likely to see them bet on that site.
If these accounts were created when just posting was enough for level up - they don`t understand it cost.
And i`m sure that they get their reward directly, without the site. Or have an opportunity to withdraw their reward without any restrictions.
