it may well be better to allow that one to be entered and to attempt to receive votes.. rather than completely leaving such a submission out of the contest...
If it's a pizza contest and someone submits an entry that is clearly not a pizza, what's the point then? If next year we make a pasta contest would you ever submit a risotto or a salad?
Are you suggesting that pizza has actually been clearly defined? Then yeah no problem. Are you going to presume that anyone looked at the dictionary for the definition of pizza or to know what is the definition of pizza if it has not been pointed out? That's seems to be the point that I was attempting to make, which is people might have differing definitions of what is a pizza if such definition has not clearly been made from the start...
For example if the definition of pizza is that it has to have tomato sauce.. or it has to have bread or it has to have cheese or it has to be cooked in some kind of an enclosed space (oven)? Can you make a pizza that would qualify in the contest without tomato sauce, without bread, without cheese, cooked in a pan or on a non-enclosed grill?
Hypothetically speaking, within a contest, pizza could have a variety of
crazy-ass definitions including
but not limited to that all pizza submissions must have some kind of a green vegetable (such as lettuce), noodles, corn, pineapple and/or anchovies contained therein.

I'm sorry but are we actually debating what is considered pizza in 2023? Just a quick copy-paste from Wikipedia:
Pizza is a dish of Italian origin consisting of a usually round, flat base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients, which is then baked at a high temperature, traditionally in a wood-fired oven. [

If the "pizza" is not baked of course it can't be considered a pizza. If someone uses cake ingredients it can't be considered a pizza. I'm not saying that all the pizzas must be exactly as stated above but at least some basic steps must be followed.
I am not debating what is a pizza. I am merely pointing out that if pizza has not been defined then it would not be fair to impose a definition after the contest has already started....
Regarding your wikipedia reference, was wikipedia pointed out as the "official definition" of pizza for the purpose of this contest?

By the way, in the end, I don't care that much regarding the extent to which the contest is fair or not - except stating my opinion regarding if the goal were to be to have a fair contest, then it is probably better to have the definitions of: "what is a pizza" for example, in the beginning of the contest, not being made up on the fly after a contest had already started.
I can't believe we're still discussing about what a pizza is because for you is acceptable to make a rice salad and call it a pizza. Please don't insult my intelligence, there is no need to "clearly define" a pizza for this type of contest, just google pizza and compare the images: do they look like rice salad? Do they look like unbaked stuff? Do they look like a mix of ketchup and mayonnaise thrown in a plate? If someone is writing on this forum it means he has internet access, they ask you to make a pizza then just google what a pizza is, that's it.
