Note: The focus above is on the Receivers on (s)Merits, that at some later point get banned for whatever reason. The Senders are generally faultless in the above context. The more people they try to merit, the likelier to hit someone that is going to ultimately be banned (specially, unfortunately, if the merited profile is of a lower rank).
