Some people pay for ads even on their social page, they do pay for those ads so that their content can appear frequently for visitors and also for their content to appear easily on search. Some of them that are making money via freelancing also spent some money to build their page. What I just feel is not right is the misleading idea of gambling that some of them try to pass to their audience.
This is very correct as some gambling ads poetry gambling in a light in which it actually isn't, some make it look and feel like you can get rich over night without actually really gambling but then you actually need to put in some work and expect to get lucky of whichbits one in awhile, some gamblers actually never get lucky but then the casinos get to be able to stay in business by accumulating more customers and so they will actually stop at nothing to make adverts that will keep driving this customers to them on daily basis.
