They are changing the votes (on mp3 voting page)

Hi Vera,
First of all, not "They are" but "he is". I am the only owner of this site. Second - I gave you the answers for your questions by email several days ago. I thought I've made the situation clear. If not, here's explanation again (how mp3 voting works):
Everyone can vote for their favorite songs no more than once a week. Usually any attempt to voting more often is catched by my script which prevent such situation. But there are some "smart" guys who found some ways to cheat the script. They may cheat automatic script, but not me, who finally check voting log before publishing mp3s. While analysing voting log, I remove all unfair votes. Smetimes the same person votes several times a day for the same song. Believe me, it is very easy to find out that this is an action from ONE person... And fortunately there are not too much such cheaters (I've found only TWO already during over one year of checking logs)
Regarding "501" - Have in mind that not everyone is everyday's visitor here and thus may overlook the time while a song is available to download. What else to do in such situation than to vote once again?
And at the end... There are many songs voted ONLY by one person week by week, twenty times just to get it. Why those people should have to wait several times longer than cheaters?
