Signature campaigns have contributed a lot in making bitcoin mainstream and in growing bitcoin community.Campaigns have also helped many bitcoin related business to establish.
I bet those whose who oppose sig campaigns are the ones who have hoarded lots of bitcoins and feel jealous when they see others earning them.
Personally, I do not agree on the latter; it's like when topics related to earning(s) and/or how to get your hands on some Bitcoins, there's always a bunch of people saying 'through signature campaigns'; and, off course, >90% if not near >95% of them have them campaigns in their signatures.
Off course not all contributors doing signature campaigns are rubbish or hollow contributions; in fact, some of them are pretty good actually! Yet it still remains a fact that due to signature campaigns, we at least can say they contribute to a whole bunch of useless and double/triple/etc posts and answers; likewise goes the same for facilitating the selling and buying of accounts. If there is money to be made, some people will just do anything to do so, and everything else comes second in line
