My opinion is that those who include Peloso have questionable judgment when it comes trust system use. They are letting this guy drag the whole system down for the sake of having an additional inclusion. Surely they don't actually think he demonstrates good judgment when it comes to forming a trust list.
Another big factor is "you can't tell me what to do with my trust list". There are some users who don't need that additional inclusion but also don't want to be seen as giving in to some elk guy and... bitchmoon or whatever the fuck they called me.
