If you are using an internet connection with a dynamic IP address, especially dial-up, you will almost certainly have a different IP from time to time. Some else using the same provider could end up with an IP you had previously.

Not too far-fetched to have random users showing up on your page if you take that into consideration. Still weird with how far apart some of those examples are...

Shinja, I think you could drop this feature
(or make it private and/or so admins can see it if need be).

I will not make my squads private I just think that the person who is doing it wants us to do that keep the 1's comming.

I say, stop obsessing over what are ultimately completely meaningless ratings. I don't agree that these have anything to do with actual critique, nor do they have anything other than an extremely minor effect on the visibility of your squads to the others on the site. There really is no reason to care about it this much, and if you didn't (or at least didn't tell everyone each week how much you do), you wouldn't be drawing the attention of trolls. I will still argue that I've gotten way more one votes on my squads than you, and you don't see me on here, each week starting a new thread on the topic. I hope this is the last one in fact.

It's tough to see your own squads get 1's, believe me, I know exactly how it feels. But in due time, just let it go and not let ratings on squad builds get to your head, such pride for ratings will only hurt you more in the future (especially if you try hard to be on top 5, it shouldn't be the case). Building a squad is something you alone should be proud about, don't let ratings effect you otherwise because that's really all it is. If you play it and you enjoyed the squad build, you alone should not take ratings into account. Comments are welcomed and important because it's good to have a 2nd opinion, and to look at situations that you might overlooked when creating that squad. I too have squads that have 1's and I didn't mind (before it was an issue, but as time goes on, it's not important). When I built something, I share it because I feel this squad fits my style of play, my personality, etc. The important thing that we should all recognize is why should ratings effect you what you think of your own squad build? If you know it works for you, keep it that way.... playing SWM isn't about a popularity contest... it's about how you understand your squad and you as a player piloting that squad is important. Because if your squad wins, do you really want ratings to effect how you are as a player? Think about it....
Don't get me wrong, rating system is good to have on Bloomilk... it's an equivalent of having an opinion, you either accept that opinion, or move on.

And to address the problems from multiple account from users in your account, it resides on ip addresses. For example, if I log into a computer from a LGS, it picks up the people who are already registered in the names accordingly to bloomilk. It might not be your computer, but if you use a computer that's already registered with a different name, it'll pick up.
