Illness has prevented maintenance on my very low-traffic (single-user?) instance for quite a long time, so I won't take it personally if you need to take countermeasures such as blocking it. I doubt anyone will be joining it to spam you as SSO signup is actually broken. Hopefully I'll be more able to use a computer properly in a few weeks and get things up to date. I wish it wasn't the case but I can still barely sit or stand upright for brief periods to eat.
