Bad Time For Ad Blocking Users

You are surfing on internet and at every site you have to watch ads reluctantly.Surely this would be annoying for you but what if your connection is too slow? Then obviously it would be a bull shit for you and you will try to find a way out of it.So ads blocker help you out of this situation.but what if savior becomes a problem.Yes a ban due to ad blocker.
Same technique is being implied by Yahoo mail. Yahoo Mail has supposedly locked the users who uses ad  blocker.when the users try to connect meanwhile the ad blocker is on they would be directed to following page.

.Users disliked this action by Yahoo and had showed their wrath  by tweeting this way.

However Yahoo joins with some other web brands. Now most of the sites are blocking the users who uses ad blocker. Users will not be able to view their mail or other content until unless they disable blockers.
