I agree with removing downvoting for both contests, or at least putting limits on that.

I believe I dedicate my time to write something funny before I submit it. Okay, they may not be rolling-on-the-floor-laughing funny, but at least they should make you chuckle. And yet, I mostly end up with negative scores; some 4-5 upvotes, but more downvotes. Now I have the Buildr Score of -2. This is very tiresome and discouraging.

I thought I’m being targetted by malicious players. And then I realized that it can’t be, because all items are submitted anonymously. No one can target just my submissions.

That is correct. It’s not just my submissions; they target everyone’s who isn’t their friends.

This is vote rigging, and it is seriously unfair. The system needs change.
