This site isn't advertised for friendship. Everyone is here for different reasons. Your pm was a bit full on. Blocking was probably a bit extreme but everyone uses this site in different ways, how someone blocks is up to them.
@ExplorerofInfiniteSpaces ok but I don't think they have changed that much. I said "probably " extreme. You asked for an opinion so I gave you one. Some people may not want to pm you saying "I don't want to be your friend " because it might lead to more questions from the other person.
