Just had an interesting experience with cj, that I thought would fit well here. We are a publisher and there was a certain advertiser that we promoted through cj which I noticed we had not received payments from since Nov 2012. The transactions were locked, but no payments. Contacted cj, telling them we had tried to contact the company without response, and they said they would investigate. Got a response back that they were trying to work out an escrow deposit from the advertiser. Duh, don't you think they would have noticed sooner that they were that far behind in payments (we're talking $1000s here).
I come to find out the company had closed their doors suddenly last month and was filing for bankruptcy. Contacted CJ with info about the bankruptcy and asked them if they were filing a bankruptcy claim against the company. They responded that I should hire counsel and pursue them myself, insinuating that they planned no action. Contacted the company and they responded that cj had been notified to file a bankruptcy claim and that once the upcoming sell to a new owner was complete that I had no claim since my commission contract was with cj, not the company directly, and the bankruptcy settlement left it free and clear of former debts for the new owner.
Personally this tells ME something very important about how cj operates and protects it's publishers. Either they did not feel it worthwhile to pursue the company or they were filing for it and planning on not paying the publishers who were owed.
Defaulting advertisers are apparently not that uncommon though. We also have an account with another affiliate co. (s-a-s), and did not notice we had not been paid (it was only $100 or so) and about 6 months later received a payment, that they had apparently taken a company to court for non-payment and won and were finally distributing the funds.
The lesson is, keep a close eye on your transactions and payments, and if they get behind at all, investigate to find out why. I would also ask why affiliate companies are not insisting on adequate account funding IN ADVANCE just like the PPC programs.
