People love bitcoin because they can earn bitcoin's free by doing a job like joining in signature campaign earning will surely take a lot of time think of it that people hate bitcoin . Also they may hate when when there is too much dip happening for unnecessary reasons making the value down of their investment.
Signature campaigns have been done well before bitcoin. I remember a website offering 1 cent per 1000 views of a banner. The banner could only be placed in forum as a signature (if the forum allowed it), payments were done on paypal and every thing ran smoothly (even better than the signature campaigns on here).
