I found this user who puts a link to a commercial extension in all answers which is obviously advertising.
The extension probably even solves the issues, but an answer that only exists to promote a product without disclosing the authors affiliation is considered spam.
So in the first question I flagged the answer as spam and moved on. But then, in others there is also halfway useful information. Just enough code to give a hint how the problem might be solved. One even got accepted.
How should we deal with such a case?
- Edit the question to remove the link? Although it might be an acceptable solution for some?
- Rigorously mark as spam? Removing potentially useful content?
- Leave it as it is? Promoting shady link placement in answers?
