If they want a "strong promotion" for the Cryptotalk forum then why do they need to change their signature campaign from Cryptotalk to InvestBox?
Just as you said, I agree to it that they kept alluring users to fell into cryptotalk campaign as it is the only campaign which:
+ Does not need a campaign manager to approve you to enroll in it
+ Pays you every single day (except the days when you cannot send your money to your balance due to wallet not refilled)
+ Needs just 5 shitposts every day to earn you 0.001 BTC
+ You can use alt accounts as well without having to worry about being caught, and even if caught, you can still continue with others, I think there must have been some account deals went through after this campaign showed up.
These qualities made them look trustworthy in the eyes of spammers /s for which they won't hesitate to advertise even the shittiest content that these Yobit guys may write in their signatures
Why not have a separate campaign for each one of them and not force their existing Cryptotalk participants to change their signature to Investbox?
I don't think they needed a separate campaign because they are keeping the source of the campaign as their website only, so it doesn't matter a lot. It should still be like, they should have discussed this shit with Yahoo and the members in their cryptotalk signature campaign to have a mutuality and an agreement of everyone.
