Are you suggesting bypassing users lot limit with vote points? If yes, then no.
If you are suggesting that as a cost to get a lot.. Hmm.. I'm not sure about forcing players to vote that have already donated for these features.. As well as this, how would you handle lot movement and expansions? People would try to evade this as much as possible.. Not to mention that shops already cost 5 vote points each, and that you can exchange them for items, don't we have plenty of uses?
