[This question's answer][1] has a couple of comments of a rather suspicious nature which left me with the impression that the question's author is trying ***really*** hard to drive the discussion towards a certain product. And indeed, a short search revealed that he is [seemingly affiliated][2] with the mentioned company. As neither the question nor any answers mention the syscomgroup's stuff directly, I wondered how such cases are handled.

1. should I just comment upon the question, downvote it and leave it as a memorial?
2. should I flag it for moderation attention?
3. should I vote to close it with some obscure reason?

For now I opted for 1. but I am open to suggestions to do otherwise.

###Edit:

As I see, the question has since been

1. migrated to superuser
2. closed and deleted there
3. deleted by Community here
4. had its poster excommunicated

The points I am wondering about are:

- why has the deletion been done by "Community"?
- having the spamming users banned would not give them the opportunity to read the community's comments - would they get the hint nonetheless? 
- should not we leave this question visible and just edit out the links and delete the spammy comments instead? It has *some* merit at least.

For the sake of completeness here the screenshot of the conversation which is meanwhile marked as "deleted":
