Comment:

 Hi @greatislander, thanks for the ticket! Sorry for coming through so
 late. This appears to be a duplicate of #20019. I'm going to close this
 ticket so that we can focus on a solution there.

 > Is there a reason for this discrepancy?

 My hunch is that it is related to how signups were originally handled in
 b2++. The username (also site) that someone signed up with would translate
 to the DB table prefix for that site: `b2_jeremyfelt_posts`, etc... so
 only a limited set of characters were allowed.
