When I ask or answer a question, sometimes the answer number is incorrect?

I have recently seen many questions where it says it has a certain amount of answers however when I look it has more, or less, than the said number, e.g. It says 3 answers but it actually has 4, 4 answers it has 3, etc. What is this? Is is a glitch or something else?

When you see more, that is just timing. It takes all the servers around the world a few minutes to catch up. When you see fewer, they were either removed by the responder themselves or they were violations of the rules. There is lots of spam this weekend, so that will happen often.

This answer is my own and is an addition to my question.
