User:R L D S not "Rids"

When I sought to sign up as user "RLDS", I was automatically informed the name is too similar to Wikipedia username "Rids"

Personally, I do not feel "R L D S" (Reorganized Church of Jesus Christ of Latter-day Saints) is much alike Rids, or to RID, a lice-killing application.

or to Raid, a cockroach-killing spray produced by SC Johnson in 1956.
