Contributors Accounts

If someone is trying to sell their existing account, it's most likely because they aren't making any money from it. If it was a money-maker, they wouldn't want to sell it.

They could also retire. There are sometimes legit reasons for giving up a contributor account. In my 10 years active on this forum, I saw exactly two legit requests, if I remember well. Both were coming from professional photographers who wanted to close their business and retire. And they enquired about how to correctly forward the stock business to their successor. 

But as you said, if you do not have a steady and decent income, there is no need to consider this. In that case, it's simply best to close the account, if the administrative work (some countries really ask for quite some administrative work to be done, even for a small income of several dollars a year) outweights the earnings.

And there is no easy path to assign a contributor account to a different person. This will be handled on a case-by-case by-case basis by contributor support.
