First: Of all you're stupid with negative IQ.

Second: The ads are server side with a maximum of 8 ads per day for each account.

Third: You can be connected to 1 account and not 2 accounts simultaneously and guess what ? that's server side too if try to connect to another account it will disconnect you from the other account.

Fourth: The only client side is the game itself so you can download a hacked client that sends fake packets to the server such this dweller is 15 level but the damage it deals is 50000 with 500000 health no wonder how the 25 level account manage to finish 80 level portal. So you are telling us that you manage to send fake packets to the server to increase the ad limit from 8 to 30 congratulatios you managed to hack Google and Your Advertising ID.

Fifth: Show us video proof or i call it bullshit and it never happend and i will delete this comment if you do.
