This is… fairly confusing.
A user suggested getting fake Sheep k-lined, thoughts?
My thoughts are, uh, let's not do anything like this until we actually know what the hell is going on. I don't see any logs of anything this alternate Sheep has done.
The fact is, "Sheep" is a pretty generic nickname. And Sheep, while cool, isn't exactly a major user, and not an op. What would anyone gain by stealing his nick to 'recon'?
EDIT: On re-reading, I'm even more confused. I share Aelanna's question. Are you sure Sheep didn't let his nick lapse? In other words, can you provide logs of Sheep having been in #site19 (IE with an identified nick) in the past month? Are there logs of any of this? Because if Sheep's nick did get stolen (password guessed, or whatever, who knows) then at minimum you're going to need logs to give the IRC overlords.
EDITx2 & 3: I did check myself. Sheep was in 19 a number of times, including today and yesterday (meaning they had to have an identified nick).
Today:
