Not "a lot", most of them were tagged by other DT members(like ibminer).As for the others, I am sure Quickseller will come up with a good solution to filter them out.
Starting from alt-accounts thread to ICO pumping accounts,I usually see comments from Lauda who investigates the matter and tags the account involved.I don't think ibminer does it on a scale as that of Lauda.
Getting a negative trust was the most looked down thing before the tyranny of Lauda.He(it) was tagging people for their personal opinion too! Red trust was losing its value, it was turning into a cliche.
Maybe you can support such statements with relevant proofs ?Also 1 case out of 100 doesn't count. I don't see how "removing Lauda" is going to restore faith & integrity in the Red trust again.
