I saw a gambling advertisement on Facebook I guess they are already prevented this because of the number of users which is below 18, also most of the gambling advertisements came from youtube, twitch, telegram and other forms of ads. The forum has a lot of members who can make an honest review than the gambling review website which is now getting paid and easily advertise a not good quality gambling platform.
Oh really in fb? But on what year did you saw that? Because I've been hanging out on fb lately but I didn't see any gambling site being advertised there except if it was made by a user but I am sure that a comment like that are going to be deleted easily by fb because like you said a lot of minors are using the platform although there are also minors on the other platforms that you mentioned but they still allow some gambling ads on them as they aren't strict as fb and maybe they care too much of the money. Don't judge all gambling review sites. Didn't you know that there are still legit and non biased review sites? A few of them are found on the forum.
