This really is a touchy subject. While I understand the points of view from all parties, I am torn as to which side I fall on.
On one hand, you have a site that is not owned by any of us. We can disagree with the advertisements all we want, but in the end it is up to the site owner to decide which advertisements are making him money. In essence, these advertisements are keeping the site running and by cutting off this resource Allas runs the risk of hurting the site (i.e. less admins, less attention to the game, etc. due to less money). From a purely business standpoint, those particular advertisements are an excellent ploy and are probably a huge money maker, hence the reason we were seeing more of them. This is all coupled with the fact that Allas offers a premium account service for a pittance ($10 for 3 months) which effectively blocks all advertisements. So if you really want to see this site continue to grow AND you don't want advertisements, do your part and kick in the $10.
On the other hand, this *is* first and foremost a video game site and, like Stugein and others have said, we should not have to worry about the chance of seeing risque pictures plastered on our screen. I know I have clicked the site during work hours, only to have an employee come around the corner to see a less than dressed female on top of the screen (Thank Bob I was good friends with the female employee). This, however, brings up the "you shouldn't be on the interwebs at work anyway" argument, so I will stop there. At home, though, is a different story. Stu's example about kids looking up quests said it best so I will not rehash it.
Well, there are both sides of my thought process. Like I said, a very touchy subject.
