I spent some quality time going through some forum rules about a couple of days ago and I found out that a lot of DT members tags accounts blatantly just due to perceived merit abuse so I came across a post made by Theymos on merit abuse, then I now begin to wonder if some of these DT members are adamant about the rules of the forum or they are just abusing their DT preferences.
If a DT member tags you for something stupid involving merit (ie. probably anything less than selling merit), then they're not going to be a DT member for much longer.
