here is an other post he use referral links but not flaged : https://steemit.com/dtube/@boxmining/8ax1mxk1
I don't know why to not treat people all the same, I hope @steemcleaners just didn't notice him and they didn't do that because he have a lot of steem power ! If this is the case tell us how much we need steem power to post referral links ?
Thank you man!
