How do you deal with a helpful spammer?
I noticed recently that a particular user (Kaye - @ ets) is always linking parts from eTradeSupply in his/her answers. Otherwise, the user is somewhat helpful and respectful, even if the answers aren't always "great" or are often "me too". Then it hit me, they work for eTradeSupply!
I slotted a few answers for moderation but this might be a heavy handed approach. That said, they might only be "helping" in order to plug eTradeSupply. I don't have anything against eTrade. I just think it's "not quite right" to plug their products here on a consistent and regular basis. They just need to set up their own fixit site IMO if they want that benefit. Perhaps someone with recognized authority should have a chat with them.
Full disclosure - I've used ETS before and was satisfied. I only link external suppliers when the part is unavailable at iFixit or has poor availability in general.
Is this a good question?
