Tim, good question, and I don't know. It's possible.

I'd bet that we could have her thrown off her ISP. Most providers don't allow repeated trolling of sites. Possibly even make it hard for her to have permanent (as in at home) internet access. Contacting her ISP is something the moderators could do (or better yet, Yuko); I think getting her for stalking would be a different matter. If she's been here several times and keeps using sockpuppets to come back- I think we might be able to make a case on that. If she tries to PM me again, I could easily raise hell about it and probably get her in deep trouble. That I found out (at least with several states) is a clear no-no.
