We can try something else too

Go to http://www.bitvisitor.com/ and use the Bitcoin Address associated with the Mintcoin SPN voting: 1K2FgV9cSgsLi9xzyE6RGTBsGxEm6NCgkN
Then every 5 minutes go back to the page, enter the new catcha and click NEXT....

This works well if we are in different time zones... BTC will start accumulating slowly, hopefully we'll get some "free" SPN votes...

Edit: I never tried this website before today, so I hope it works as it is advertised...
