Wow!!!
I need to configure my routerOS v5 to block websites like youtube, facebook and porn sites for a company. This I need to do for the users but the directors should be able to acess facebook and youtube. The IP addresses range from 192.168.0.1 to 192.168.0.50 and the IP for the directer's machine is 192.168.0.10
My main problem as at now is that I have not even managed to block sites for all users. I tried to block facebook.com with the rule "Firewall Filter Chain : Forward Protocol : TCP Port : 80 Content : Facebook Action : Drop" but facebook still opens with https://www.facebook.com
I have tried to block youtube with the same rule but it does not accept.
I have tried to post earlier but I am not being helped and I have a deadline of tommorrow. I would really appreaciate if someone could assist. If someone can explain with an example it would be really nice.

I often see that some forums can block IPs of the comers, but I don't know how to do this. I know that there are website blocker to block certain sites.
