I received a warning e-mail from a married dating program I promote. they are telling me to stop using email blasting methods, which I like to do because I have received good results. The e-mail they sent me says that if I don't stop doing "such practice" they will hold my next payment, which is around $1,400 (my biggest check so far).. can they ask affiliates to not use email blasting? how do they know I use e-mail blasting methods?
