Every newly registered user shares their IP with me. When they sign up, their IP also shows up under my IP history. So searching for shared IP's always lists me.
Any idea what could cause that?
Pretty sure I checked with Andy to make sure his was patched for that sort of issue a long time ago. Basically any addon that uses a data writer to make a post or conversation needs to specify to the data writer not to record an IP. In conversations the IP will share with the user triggering. When it comes to threads and forum posts it seems a bit random but always a visitor, often a google bot, probably due to cron triggers.
