For a while, I've been getting these errors showing up in my PHP log:
Question2Answer fatal error: User registration is handled by external code
I assume an ordinary visitor has no opportunity to create such an error, so this led me to assume it was a spammer of some sort. So, I started logging IP addresses for this error, and it turns out to be a single IP address:
122.150.203.91
trying repeatedly to register on my WP-integrated Q2A site, which of course is impossible.
A reverse IP lookup gives the following domain:
122-150-203-91.static.dsl.dodo.com.au.
Any idea what this might be? If it's a spammer, then here's their IP for everyone, it seems like they're sniffing for Q2A, so better block them.
