I block people who repeat the same thing over and over on forum sites.
On one of the sites I was on there was a guy that kept talking about Yu-Gi-Oh cards on every post even though the posts had NOTHING to do with Yu-Gi-Oh. I got annoyed and blocked him without telling him. He somehow found out and freaked out and was asking other people on the site to get in contact with me and ask for him why I blocked him.
The same exact thing happened on another site with a chick that talked about nothing but Sailor Moon and another guy who was obsessed with a Harley Quinn.
Once I block them, I no longer saw them and it became so much easier to have fun on the sites again. Is it normal?
