This situation was well expected for me, I know Yobit will start their own exchange campaign eventually. Although everyone know cryptotalk was a part of Yobit, but it was quite different for signature campaign. Everyone leaving their own opinion here, but actually we know the reality. I believe you will even find scam accusation against Binance. So it's not very very big issue for a exchange and just leave that chapter for a while.

Their current advertisement for investbox which is pretty clear of a ponzi scheme. I will never satisfied whatever they will answer about 10% daily return. Only a stupid could trust that 10% daily return isn't ponzi scheme. They have earning even from trading and listing fee, so that scheme could run longer, that's only different from other ponzi scheme. That's only one point I found, but not sure how long will it run.

Personally for me, I don't like to see such as advertisements on the forum. I know nothing will change for my opinion because a major part of signature participants are doing their campaign and tagging them is quite complicated.

I don't wanna force yahoo62278 or their participants to leave campaign, but yahoo62278 should reconsider decision about campaign since it was not a part of contract at the beginning of cryptotalk campaign. I know if you leave they still might control their campaign from their exchange, but it doesn't mean we should give them freedom to advertise such a ponzi here. If you are worried about spamming  then it's the concern of forum admin and moderators, not for DT members. Because we have experienced that admin ban signature for spam reason and it was happend with Yobit.

So if yahoo62278 leave this campaign management then I believe Yobit signature campaign will ban once again. So by leaving this campaign indirectly you will help to ban their campaign from forum. By continue this campaign management will look like we are going to legalise ponzi advertisements on the forum just by preventing spam since we believe yahoo62278 helping prevent spam from their campaign.

Everyone have their own choose, still I didn't think to tag participants, but not sure about future. Likely some DT could take action and its totally depend on every individual person.

Yahoo62278 is well experienced and reputed manager so I believe he will take right decision. Whoever worried about spam, then I will say don't worry, because admin have power to ban and prevent spam. This is the part of admin and moderators job.
