PTC,manual,auto traffic exchange and similar not allow on all ad networks.
This is totally against the rules and I hope you get banned
I don't know about the other ad networks, but I can't seem to find that method prohibited to a-ads and I can't also see it on their ToS here:
https://a-ads.com/terms_of_serviceAs I've read this post of the A-Ads admin:
https://bitcointalk.org/index.php?topic=140822.msg3344054#msg3344054It seems that he never mind the traffic coming from bots or traffic exchanges because they are able to separate the different sources of traffic, IMHO.
EDIT: On the other hand, we can't use the OP's method to a free hosting sites because of the limited assigned bandwidths on their free hosting service, most of the hosting networks that give free hosting will suspend your account if they will detect that your site is exceeding it's bandwidth limit (like hostinger),
but I do not know if blogspot.com has limitations on bandwidth. Blogspot.com can handle unlimited traffic. But of course, technically, it is cheating.
