Pornstars that I'm sure think they're "so cool/awesome/unique" by adding 2-3 xes on their last name. "Wilcox" isn't any neater a name when it's spelled "Wilcoxxx", neither is "Banxxx", "Foxxx", "Staxxx" etc. Just because you work in the adult industry and want to try and make a play on words or something doesn't mean you should, it just looks fucking stupid.
Not to mention how then every other person needs to adopt it as well as if it's completely new and underused, just because they want it to be eye catching or whatever.
