If the majority of people honestly agree that a rule should be added, changed or removed, then it should. A site should always cater to the majority as long as it doesn't compromise the site in any way. I think that as long as enough people care for something, Jacob will listen and do the best to see that action is taken to address the need.
An example of something that could change would be no guro (guru?) allowed, as it's just to the taste of Jacob I think. If the majority of the user base wants it, then it should be allowed.
An example of something that will not change is the no loli allowed rule. It doesn't matter if the majority wants it, as it compromises the site. The ads say we can't have loli and they pay for the site to run. To go against that rule would mean to lose their revenue and that is a bad thing.
The best place for the suggestion should be in such. Suggestion section.
