In Virgil's absence I've taken a look at the Ovalcircle account. It has a seemingly-valid email address. (Used mailboxtools
to validate email)
There are no other indications of issues, except logs showing numerous invalid login attempts with password errors for Ovalcircle.
The way I see it, if these two accounts belong to the same user, it raises some questions, since this account has been established some time before the reported issues with the Ovalcircle account. Additionally, this account also has a posting history on site. I would suggest that if this is in fact the same user, the status quo be maintained. One account per user does seem to be a good policy, although it's not something we actively enforce.
PS. I did some other research, but the results do not bear discussion in a public forum. I'll share those with Virgil next week.
