>>5919632People post stuff in a public forum and then get annoyed that the public responds, or that they have to deal with other human beings. People act like Twitter is a private diary and that is just incredibly stupid.
Having said that, I've blocked a few people for being annoying, and I've been blocked by others for petty reasons.
For instance, if you have ACAB in your profile, you're probably an irritating little gnat, so that will make me much more prone to blocking you.
