I just received this email from XYZ@SOMECRYPTO.com (XYZ and SOMECRYPTO are not the real names):
I’m XYZ, a community member of SOMECRYPTO, a high-throughput and high-security blockchain platform. Our community has proposed a stackexchange Q&A site for users, enthusiasts and developers of SOMECRYPTO. We were wondering if you could help by pledging to our proposal on area51 (https://area51.stackexchange.com/proposals/0/SOMECRYPTO) via your stackexchange account. In order to compensate you, we offer to pay you $10 in SOMECRYPTO and $10 for every friend you refer who has 200+ points on a stack exchange site. Please check this small video for reference. Best Regards, XYZ
Question: Do we have a policy about such monetary arrangements?
For instance, in the Wikipedia community there are special rules surrounding paid participation.
By the way, I have never written anything or released any software or asked any question about cryptocurrencies.
