My uni don't allow me to play certain games but runescape works with a bot client?

So basically, I'm in uni and my uni don't allow me to play online multiplier games there's too games I know I can play which is 8-ball-pool on miniclip and runescape in a powerbot client.

I found it quite strange how it worked in a bot client is there any way I can do this with other games I really would like to do this with Minecraft.
