Helen, fantastic find! I was trying to post a little earlier and got sidetracked with a phone call. Here is what I discovered:
I have just been timing Conejo's votes minute by minute. They are generally gaining at the rate of 1 to 2 votes per minute from 9:54 AM to 10:20 AM (with 3 exceptions in which they gained 3 or 4 votes from minute to minute). I tried to do the reading just as my computer clock turned over to the next minute, but my computer started balking a bit and several seconds elapsed before I got the new number a few times. There does seem to be a pretty consistent pattern of 1 to 2 votes per minute, which does seem to me to be a little suspicious. There may be a voting device of some type being used. I figure in the case of the 3 to 4 votes per minute the extra votes may have been "real" votes.
I am sorry to be so distrustful, but I encountered very obvious cheating in a small online contest. My sister and I were timing in different states and found that when the person in No. 1 position saw that No. 2 and/or No. 3 positions had gained a few votes, he apparently turned on a device that fed in a vote for himself every 30 seconds. He would let the device run for a period of time--sometimes hours--and then his votes stopped. The sponsors surely knew it was going on, but didn't take any action against him and he won the biggest prize. And the essay he had entered was a poorly written paragraph with all sorts of mistakes. It was pretty apparent no one else was voting for his entry when there were really good entries.
The above experience has made me wary of rapid increases in votes, esp. when the votes come in at regular intervals. There must be all kinds of voting devices for those who want to cheat. Some devices may hide the individual computer number, or auditors may not check votes thoroughly to find irregularities.
Because of the regularity of votes for Conejo--1 to 2 per minute--during a surge time, I can't rule out some voting device.
But Helen has found something concrete that is not permitted. I suppose it is possible that Conejo doesn't know that getting votes in that manner is not allowed. But thank goodness Helen found the site right now, and Vivint can give Conejo a warning. The WPI still has a huge lead.
