Well, at least this discussion has opened our eyes to the users who have morals, and those that are willing to lie down their morals for gain. The moderators, and Yahoo's opinion matter not, and even theymos' doesn't matter on this particular issue. However, what you decide for yourself does matter.
You either choose to continue earning a good living with Yobit's shenanigans or you keep your respect. I don't think you can keep both. Also, no one here is blaming Yahoo, and I'm not sure why users are even mentioning that fact. No one here is calling out Yahoo. Its quite clear that Yobit have terrible customer support, and communication even with someone they have hired.
Considering that its a law to offer customer support here in the UK, and they are willing to put that so low on their priority list speaks volumes. The whole company is unprofessional, and all they care about is earning a quick buck as evidenced by this InvestBox shit.
No matter what one's moral views are, a BTT user should not be penalized for promoting one of the most well known crypto exchanges.
Many crypto exchanges are engaging in unethical practices like fake volume, pump & dump schemes, shitcoin IEO's, etc. and yet they are still highly popular because they also manage to fulfill some really valuable duties like market efficiency and liquidity.
As numerous users have already noted, an analogy can be drawn between promoting Chipmixer and Yobit's InvestBox:
you can choose to be a smart investor and use Investbox to make 0.1% on your BTC monthly without ever investing in any of the shit coins, or you may choose to be a gambler and pursue some short term wild gains in the massively inflated shitcoins (similarly Chipmixer service can be used for illicit activites, yet the marketer cannot and should not be held accountable for a potential abuse of a service that has other net benefits to the ecosystem)...
I agree the wording of the signature can be revised to be more honest, but trying to frame hundreds of Cryptotalk / Yobit participants would be one of the most harmful things this forum can do to herself and its user base...
