I’m guessing I either had answers deleted a long time ago to the point of me not being able to pull them up & not knowing I might be able to revise them & not have them count against me. Also I did not know a deleted answer can hurt me.
Also it’s possible that my answers could have been seen as too self promoting as I have explicitly answered questions that relate to a project/app that I’ve spent several months, if not a few years, creating. (Despite that unless my project directly answers the question I don’t spam this forum or any other - still I assume the algorithms used to keep the site clean have very low tolerances for reasons.)
