@Caleb ^^^^ This really isn't the way SE is meant to work, correct? (I'm sure there are other "usernnnnn"s for this same user) -- but I wondered if there was even some sock-puppet (though probably not), but it is odd in this model. (Odd, too, to see the same "identicon" with three different user numbers...) @JonEricson
@Dɑvïd The identicon is Gravitar, which uses a hash of the email address. Ergo you can see that those ore all indeed the same user. There isn't really any sock puppetry going on (most of them don't even have enough reputation to up-vote) but it's pretty obnoxious actually.
@Dɑvïd I've requested they stick to one identity; however pseudo-anonymous they want it to be is their business but that's different that flooding the market with aliases.
@Caleb Yepper. Thanks - quite possibly no one would notice this plethora 1-rep answers of an eerily similar outlook ostensibly from different users. But it also contributes a certain weirdness that we can well do without. IMO.
