I wonder, I bought a 10k ad thingy, and what I wonder is will it show only 10k times, or does the limit refer to 10k clicks?

It shows 10k times.

I'd assume it's 10k show ups. If it would be 10k clicks some banners would be around for decades. XD

it'll show up 10k times before disappearing.

ah thanks guys. now, will I get a message before it goes down?

yes, you will get an event telling you your ad has run out.

great thank you very much georgie. Then I know mine hasn't gone down yet
