I delete pileups of 20-30 or more questions because it makes me feel overwhelmed to read and answer them all. And deleting everything by itself takes too much time. If it's been 3 or more days and I haven't answered it, send it to me again. (Friends/people on other sites just tell me you're sending it again on a social.)

I do TRY to answer anons/friends/following recents that get grouped in with the pileup before I purge my inbox, but mistakes can happen.
