And, that's what happens when you advertise online (groups/forums, etc) with just an affiliate link. If you lose the account, all your advertising/marketing is gone. And, then you're starting from scratch with promotion, running around trying to put out new ads/articles, promotions, etc.
For this reason, I use redirects from a subdomain off my main site (such as assigning an affiliate link to a specific subdomain to redirect to main affiliate so), so these links can be easily modified on a whim.
Not that it would ever happen, but if I ever lose access to any of my affiliate accounts, I can go into my control panel and change those links and redirect to the new affiliate link. In that way, I don't have to start my affiliate marketing efforts over for that specific product. All the links on every site/group/article that I've ever published linking to that product are instantly updated.
This idea also works if I decide that I no longer want to promote a specific product, that link can be salvaged and reused for a better one. This especially works when advertising in Facebook groups and forums (that allow links). This would even update your links on your Facebook page instantly.
