I know, there are many hoster promising unlimited webspace but you admit it too, is it serious? NO,
or they say "unlimited traffic " and afterthat they say "fair use" what is fair use?
Hoster A: he is serious says "hey my plans here 1 promise 1 gb traffic 1 gb webspace and want for it 1$
Hoster B: he says unlimited traffic unlimited webspace and fair use, for 1$
so a person who searches for a hoster, decides for liar hoster so Hoster A has disadvantages even he is much more honest.
The client, who has no ideas from hosting has been lied,
Hoster A, even he is serious, has lost a client
