How long do advertisements last?
All advertisements last for one month. However, users may contact the team of RuneList if they wish to buy out an advertisement for a longer period of time.
Are advertisements strictly RSPS-related?
No. You can setup an advertisement for (almost) anything, as long as it fits the dimensions (728x90 & 300x250) it should be good to go. If you want to make sure your advertisement is following the community rules, feel free to message any Manager.
