I started flagging bitconnect posts days ago. That and Genesis mining referrals are becoming a disease spreading across steemit.
I'll also flag posts that are just pics or vids with a stack of referral links at the end no matter what they are for. You want to use your referral then fine write something original about the site. No copy/paste from the site, no copy/paste from bitcointalk. No pic of some chart or graph. Your own words about your experience. And no I made x amount since y isn't good enough.
While how you use your flags is completely your decision I think what you've described is over flagging. The danger of over flagging is that you are far more likely to trigger a flag war and incur flag bots.
Interested in your opinion actually... could you check this out and see if I followed the recommendations you mention... please note I posted the piece last night and only now came across your comment.
I welcome criticism and praise equally as I'm new to this blogging thing. :)

Actually looked at that one last night. Looked good to me.
