A Question for Hosts re Voting Patterns

I wonder if other hosts are also experiencing a rather unusual pattern of voting by one very generous DPR member, whose ID number is 369AB021. In recent weeks, he/she has voted in three of my challenges. The first one, he/she gave 100 votes of 2.5 to all entries. Since then he/she has generously voted 100 scores of 5, and more recently 82 scores of 5, (there being only 82 entries.)

Since he/she can't vote for his/her own entry, it doesn't appear to be an entrant in any of my challenges. (There would have been 99 scores of 5 otherwise.)

I have never had any meaningful assistance from DPR Head Office about vote manipulation etc, so I'm not going to waste time chasing them.

I guess that folk who have put in fairly ordinary shots into the challenges, and have placed near the bottom, will feel pleased that at least one person liked their shot enough to give them a score of 5, not realising that the scores have all averaged out!
