I hate those sites that you hop onto that don't let you hit the 'Back' button out of there. I constantly run across these sites, be it porn-related or not, and it really pisses me off. I usually accidentally end up on these sites via search engines. Why the heck do these sites not want me to hit the 'Back' button out of there? Do they think that preventing me from leaving their site will make me wanna hang around and look around simply because I'm too lazy to close a browser and open a new one? Wrong! It makes me hate the site all the more. And keep in mind I'm not talking about those sites where you can exit by hitting the 'Back' button twice quickly. I'm talking the ones where you can't get out of no matter how quickly you hit the 'Back' button.
When I go looking for action figures or comics to buy, I usually go around price matching for the best price (ie: the place that has the best shipping charges). Therefore, that means I'm constantly checking out multiple sites, leaving and entering and so on. The problem is that, on occasions, I come across a site that doesn't let me leave via the 'Back' button. They simply trap me on their site. If that's the case, I make sure I don't buy from that site. If I am a potential customer, why would you want to inconvenience me by forcing me to stay on your site and having to open a new browser? Inconveniencing me make dislike your site and makes me more unlikely of using your site in the first place. That's not good business, to inconvenience a potential customer. For instance, if I need to buy something at the store (ie: not online) it's like me browsing a store and the store suddenly locking the doors behind me to keep me from leaving.
One of the most annoying things about the Internet is the dreaded pop-up. You're surfing the Internet and suddenly, a pop-up window pop's up when you visit a particular site. It's annoying having to deal with pop-ups since they usually block the site you wanna view so you have to take the time to actually close the pop-up window. Of course, you can easily get rid of that by getting various pop-up blockers like Zero Popup or getting the Google Bar that has a pop-up blocker built in. Nowadays, since we don't really have to worry about pop-ups, we still have to deal with those sites that prevent you from leaving it via the 'Back' button. These sites I find worse than those pop-ups. Getting trapped on a site sucks.
