I noticed it was probably Will right away, but I don't really see the problem. It's a reasonable post and he could make (and probably has) non-obvious sockpuppets if we wanted to. You can't credibly threaten to ban non-obvious sockpuppets so why ban the ones that at least let us know who it really is? So long as the sock-puppets behave themselves why does it matter?

If people think the thread is a good idea upvote/participate. If they don't, don't. Whether or not the sockpuppet Will uses is obvious or non-obvious shouldn't make a difference.

The use of sockpuppets doesn't seem problematic to me unless they're being used to bolster support for something the true-user has a vested interest it. I.e. if someone with some responsibility did something wrong and they invent a sockpuppet to defend themselves. But they seem really unproblematic when they're obviously sockpuppets.
