you make it seem as if I cant create spam or bot accounts because of mana? I'm pretty sure thats, not the case.
just because it has some level of expense to it does not mean they stopped it from happening...
self voting can be done by simply having a secondary account that trails your posts or comments and votes for them.
nothing was solved by this... it just made the problem form differently.
That may very well be, but this is an address to these real problems. I'm not sure, like you, if this will have any real effect in curbing bot spam but won't time tell very shortly?
