I have a few comments on fb mostly negative. I’m going to delete them as soon as I find out how to. Some have profane language!
Hi Sunga17 - welcome to the Forum! You will find that people have nothing better to do. To delete if you hover in the right corner of the comment box you should get the option to delete and or block. Block any nasty people.
To block words just go to your business page on Facebook. Hit settings, then scroll down the page until you see page moderation. Then you can type all the words you don’t want them to be able to say.
