We don't need the data to tell us that, however. Anyone who has been here for more than a month knows that the spam problem is because of these altcoin campaigns. When they can create the payment out of thin air with no cost to themselves, they are happy to pay for any old trash.
I believe the reason altcoin campaigns are the problem is as a result of the highlighted sentence above. I'm in support of altcoin campaigns not having the privilege to pay participates in their worthless token but not also in support of all paying in bitcoin. They should be given a chance to pay in selected altcoin. That's why I previously suggested this
there should be selected altcoin used for altcoin bounty campaign payment. The forum has grow more than just bitcoin. I believe that's why we have grin as a payment option now. So this is my suggestion, every altcoin bounty should pay their participates in the token of the blockchain their project are developed on.
Example, If your project is based on ETH or EOS blockchain and you want to run a bounty campaign participants will be paid in ETH or EOS and not your worthless token. I believe this will also have an impact as they got something to lose if shitposters are been paid.
Altcoin campaigns have higher number of participants and paying all of them in bitcoin will cost them more than in most altcoin like EOS that has zero fee (not endorsing any coin here) just explaining my statement with example.
