Insane in term of too cheap or too expensive? for me the rate is pretty cheap for a month, although the avatar does not contain a clickable link, it is worth for few people to milk every penny for their posts
It is too cheap in my honest opinion, an avatar can 'bring' more visit ((also if it is clickable) respect than a signature, because an avatar appears more than a sig ad (by the way this is only my personal opinion, and a good rate could be 0.10 btc per month).
I do think the rate is decent, since the picture isnt clickable, but an avatar + signature could be a better campaign since an avatar will actually show a part of the sites, and the link in the signatures is clickable and it is weird to see someone using A sites signature campaign, B sites Personal message campaign and C sites avatar campaign
agreed with you avatar + signature campaign would be more attractive than use 2 different campaign, i think avatar is campaign will be nice option to get more views to any link.
