Before I execute my idea, I was wondering if I could run a low-resouce-using PHP bot for a chat. I haven't seen anything against it in the ToS except the resource clause. Just wondering how it settles with you guys.
It mostly idles, and doesn't say anything, but people can command it to do things such as turning text into ASCII art, and procuring random "8ball" sayings.
I don't think it would be a good idea. Also everything you do on your webspace has to do with what your site is about and should only be used for your site. So running something that doesn't have to do with your wouldn't be allowed.
