I saw someone offering $57 custom splashes. His example for brainy clixsense one nice. I like banners he made alot of ones top clixsense promoters use I plan buy bunch more. I had bunch custom banners made for clixsense. They get higher clicktru rate. Some fivierr people offer 6 or 12 for $5. The default ones work but custom way to go.
So not only need spend money on banner ads but also buy few custom ones every few months. I put my name on mine its got such bad reputation yet see people use them.
Bad reputation I find handy I got lower dispute rate as people buy ones over looked info (or my dirt cheap get them too than they keep buying see that others wrong). I not only grant refunds I too lazy take down their ads so they get money and free ads I had people buy once saw that saw results worth buying later on. I recommend having good reputation but once bad can be liberating as just hit refund button and not have to put up with them blackmailing you as you do not care. I get reputation sites offering remove bad feedback like I pay. I known owners way worse than me not known as they got someone take heat or use whois protection services.
