The point is to efficiently funnel newer players into selected servers. Balmung NEVER would have become the bloated mass it is currently if they had bothered to label two or three servers as designated RP ones. Since there's no official tagging, everyone just got told that Balmung was the RP server. If you wanted to RP, you should go to that server and not look at any others. If Mateus and maybe another server were officially designated RP servers, then newer players(or ones that are just fed up with Balmung things) could start a healthy RP community there.
WoW has plenty of RP servers, and yes there is a Balmung among them, but there's healthy RP communities spread among all of the other RP servers too.
Saying it will increase harassment is just fear-mongering. Jerks will be jerks. There's nothing inherent about RP that will trigger some kind of latent toxic personality in an average person. Report/ignore them and move on.
