@Nyssa The number of votes needed depends on the vote totals of both the question and the answers.

FAQ: How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?

> It takes three votes to delete; more if the question is popular, but ten votes at most.

The link is to this answer: Should delete votes be limited like close votes?

> Popular questions require more deletion votes to be deleted, at a ratio of 20:1 - a question's popularity is defined as: question score + top-scored answer score. For example, a question with (question score 15 + top answer score 5 = 20) will require 4 deletion votes (3 base votes + 1 popularity vote).

> The maximum number of delete votes needed will not exceed 10.

In this case 164+18=182. So there are "9 popularity votes". Together with "3 base votes" it exceeds 10.

So only the top answer counts (and the question). Thanks for the input!
