Description

Context: There are some polls that don't have feasible options to vote. One such example is [we in 2021](https://governance.decentraland.org/proposal/?id=7f4a1f60-c838-11eb-9861-ebb8fcfd58d2) or [How many people...?](https://governance.decentraland.org/proposal/?id=f4ac0d20-bf2a-11eb-8849-33c326fb5301). The poll [Should we be actively seeking developers for game design?](https://governance.decentraland.org/proposal/?id=9adc5520-e018-11eb-a20f-d75df7f87ed8) came up in a conversation as an example of a poll with more than two "no" options. It might be interesting to have the Snapshot frontend automatically generate an option that signals to the creator of the poll that the question was framed incorrectly. It might bring us some vote dilution, though. I propose that the votes towards the "Invalid" option don't count towards the threshold of 66% to accept a vote (for example, if 1M mana votes no, 3M mana vote yes, 2M mana vote invalid, that would count as 75% acceptance -- only the 1M of the "no" option and the 3M corresponding to the "yes" option would count).
