I’ve replied in here so as not to go too far off-topic in the other one. 
Posts are only hidden if enough members flag something. To be honest, it doesn’t happen that often as Brenna (our delightful, yet all-powerful AdminMod) normally nips in and edits out the rule-breaky bits before they collect enough flags to be hidden behind that ‘click to see’ screen. She only works office hours though, so the community flags can be quite useful over the weekends, etc.
Brenna will edit out any overt recommendations for non-Lovehoney toys/stock when she’s back in on Monday, but you can edit your posts before then if you want to (you should have at least 24hrs to edit a post).
I think the basic rule of thumb is to avoid sounding like you’re saying ‘don’t buy from here, go here instead’.
Hopefully that makes sense.
