Not really, I doubt they will be tagged because a few months ago, cloudmining.scamsite had a sig campaign. They provided no mining proof, no select able pools or even pictures of their mining hardware, so it was pretty obvious it's a ponzi. People wearing the sig were not tagged though, since they were probably un-educated and there is a (really) small chance that it is legit. EcuiMobi had a post regarding that on doublebot's sig campaign page I think. Too lazy to find it though.
