Quit encouraging them. Both the casting directors and the "how do I get all the camera time" crowd.
I do often enjoy the villain, but I do need to "love to hate" them rather than just "hate I even know they exist" them.
I don't mind that the villain gets more than their fair share of the screen time, but only when what they are doing actually has to do with the game, rather than desperation to keep the camera on them and random crazy evil is all they got.
It takes a bit more than claiming you are there to win to make me think you are actually using the evil for a purpose that has to do with the game. At least have some subtlety about your wheeling and dealing with the alliances. It is more fun, at least for me, if it legitimately takes awhile for people to figure out what is going on. Just making it through because they only cast people too stupid to catch on (or too ineffectual to do anything about it) for a few episodes so they can get their villain story for the season just annoys me. I know you need a bit of stupid cast on pretty much any show, but these "super-dupery-doo-villains" they cast these days need way too much stupid surrounding them to last long enough for a good story.
Now I am still trying to get the bad taste out of my mouth left over from gNat-a-LIE and Ronnikins from BB so my tolerance is a bit low.
I know the days of the villains who actually have a good shot at winning because they have some charm and intelligence and game may be over, but can't we find something better than this to cast in order to replace them?
That he actually thought to look for the idol does give me some hope that maybe under all that attention seeking there lies something worth loving to hate, but I can understand all the "he only looked for it or found it because production gave him the idea or location" conspiracy theories going around.
I just worry that most of the early villains were cast more by happenstance than by design. Unfortunately now they are trying way to hard to get one, and the quality has gone way down, IMO, YMMV.
