Every now and then, when reviewing the New answers to old questions list, I find answers recommending a third-party tool or site.
They're probably not the best kind of answer but in the context of the question it could actually be relevant and be contributing something.
But when we see the same user posting several recommendations for the same product, and the specific user just signed up, maybe something spammy might be happening (or it could be an enthusiasthic happy user/customer).
Seems like there are users who (apparently of course) just sign up to recommend a product or tool. Sometimes there is more than one new user recommending the same product around.
Should we flag those answers as spam?
