List of Aegis FCs by size

Some odd FC names come up on the very first page:
wWtuGzJ
kkc
JQksSdL
pCYUJlD
ogcIhNz

Membership is always 48~50 members, almost all level 50~60 BLMs [with one or two buffing jobs] with AF1/2 gear sets with very similar sounding names. Not to mention the FCs are usually recently started and with closed recruitment status.

The odd thing is you don't get RMT adverts on Aegis these days. The last RMT ad I've ever gotten on Aegis was in late 2014. So what could be worth going to all this trouble?
