I nearly lost a Facebook page when warning victims some time back TalkingFlowers.
Do you have a Facebook Page listing these fake Romance Scam pages ?
Though I am currently concentrating specifically on scam vehicle adverts on Autotrader UK I run a rolling thread on Scamwarners here
https://scamwarners.com/forum/viewtopic.php?f=6&t=82849&start=930… that works well. I mention my thread simply because you could use a similar format in the Romance scam section and, by adding new profiles, it acts as an archive and keeps the thread high in the listings. SW gets posts quickly listed on Google which helps any potential victims to find your warnings. With each post I also have general warnings about the type of scam.
Though I have no direct contact with the ad site on which I look for scams they do react promptly to the reports I submit and I can't help but feel that knowing I will list every fraudulent ad puts 'soft pressure' on them. I'm not looking to have a fight with the ad site and I could be more aggressive but that would be counter-productive.
If you undertake a task like this the only thing you want to achieve is to be effective and you have to design your tactics accordingly.
