They are ordered based when you join I believe, so you may want to look at the last page ASAP.

Like I said in a different thread, you do not know if the person inviting them is doing it by mistake or trying to blacklist them or what, a simple solution is just have right click >report for RMT, auto ban them from the network, while sending the notice to a GM. This way if it is abused and someone does that to abuse it, the GM can go after the abuser as well.
