Almost every submissions we came across we noticed a message from you begging for people to check out your submission, it's common decency not to do this. We can't guarantee a fair vote on your submissions anymore and thus it has been disqualified.
Why isn't the rating fair? The other participants still rated the game, and in the end, the game receives the average. Rating others' games and asking for a rating back is very common in all the jams I have joined over the years. I have never seen someone disqualified for it. It seems very harsh, especially when it was not forbidden in the rules.
