Talk about the most intolerable mobile ad type

These days my friends and I shared our feelings about mobile ad with each other.
As for me, banners and interstitials (if not too frequent) are acceptable; push and icon are intolerable. However, if the interstitials are too frequent, I will uninstall the app without any hesitation.
As for some of my friends, any type of ad is intolerable. Once they find ads in app, they uninstall.
As for the rest of my friends, they do not care about mobile ads. They only focus on the app itself. If the app is interesting or effective, they will keep it.

How about you? Could you share the most intolerable mobile ad type?

I am very logical in my approach. I don't mind very much ads, because i know developers need to eat too. I'm more concern in the security aspect. So, as long as the banners are not vomitive and i get added value, it's ok by me
