Does having 1 posters "suggesting" a seedbox site constitute advertising?

I've noticed a lot recently that someone will post in the seedbox section of the site asking for "suggestions" of what kind of seedbox to get, only to get a massive swarm of 1-2 post blatantly obvious site owners to post on the thread saying they "recommend" that site. At what point should that constitute advertising rather than honest recommendation?

The seedbox section is the only way for seedbox providers/Resellers to help members choose which service, Then members give their feedback. If someone is spamming advertisements then report it if bothered by it.

If you see someone do it repeatedly then report them. That is all that can be done to be honest...

It's pretty easy to spot who is playing smart and "recommending" a site. Report that so the post can be analyzed and see which are the users real intentions.

this is irrelevant! I don't think is the most viable solution.
