Hello @Christina1105 < how did this Guest work out in the end?
I have no problem with anyone restricting knowledge online in their profiles that are visible online because there are people who for whatever reason may have and are still experiencing Personal Safety fears so need that added layer of privacy and safety in their lives.
I have hosted someone who used initials because of their job and rights to a private life.
There is far too much personal information belonging to all of us online that has been collected using coercive ways that is a legal minefield.
