i still feel like sharing information people could use to earn money anywhere should not be flagged ; i may have spammed his feed sure - but at the very least ; unfollow, each post is different, i would not consider it spam, although i have posted one after another give or take 5-10 minutes .
So in that regard yes i can agree with flagging maybe the original intro post to the tag itself, and maybe giving a reason for it ; but not giving a reason why is just confusing to be honest, let alone flagging 4, then another 4 an hour or two later ?..
