Not technically true as far as I understand.
One, if I understand mrkgnao correctly about issues with MaGog, you can only log into three different accounts in a short space of time before being locked out.
Not sure what this is all about, but I'm fairly confident it can be overcome.
Two, you can only visit the forum pages about 500 times before you get locked out, and that runs out pretty quickly if you're opening every single thread to find someones posts to down vote..
So while you could probably do some damage I don't think it could really be too bad.
Which is why I'm fairly sure a lot of the downvoting isn't actually done by bots at all.
Out of curiosity I used Fiddler to take a look at the cookies sent to server. I'm pretty sure that a cookie can be made to last indefinitely, because the numbers, which are incremented with every new issuance of it are easily identifiable. What I don't know if they are being checked server side for being equal to what was last issued. If that's the case then it becomes more difficult but hardly impossible.
But I do agree that the system needs to be changed, but using Regals as your spokesman is not exactly the best bet on that account.
No, no, no. He is not my spokesman. =) I'm my spokesman. I merely pointed out that what he says is accurate (in this case) despite of who he is. I'm not endorsing him or his behavior. If I did, I'd just behaved that way myself, wouldn't I? =)
