I am not the most tech-savvy of people and careless at times....but when I had come across that today as I was idly looking at my account....I almost had a frigging heart attack. Sure, you can clear it but you cannot stop them from collecting that data on their own server...it is there forever as long as FB exists, you cannot delete their copy....AS YET! So from now on.....a clean computer used only for business only (check, I have that), a clean trackless VISA (to get), new FB account, new eBay and Amazon accounts, temporary fake telephone #, always using a VPN on Brave search engine, using Brave (I have stopped using google a long time ago) with DuchDuckGo on top as an onion....let their hindermost parts track that. This is where they are making their money today....on information exchange. We made them, and we can break them. Now I am waiting for a truly free speech engine to make its appearance.
