Probably. I know we have a bunch of alts around here. I just have no evidence to suspect that any of them are whomod.
Or maybe...just maybe...they're not alts at all. Maybe there are actually a bunch of people out there with a similar viewpoint.
(Then again, it is possible to create the perfect alt id that nobody suspects is an alt. I wreaked havoc on a Daredevil message board under multiple alts, and nobody suspected me until I got my alts confused. Since then, I no longer use alts.)
