Good point, if you can avoid those contents then you are preventing the possibilities that it can affect the way you think, there are many influencers even some of those that at first they've got decent contents but because of high demands and good offers they allow those gambling business to penetrate and change the directions of their contents more on the money side, but moving back to that sentiments, if you don't mind those kinds of contents and you don't take time or invest time to learn about it, then there's nothing to worry as it won't pollute your minds.
But I have to remind you that if you don't want to be influenced by gambling content, the first step is to report the content and choose a statement that the content does not match what you watch on social media. We need to know that if we watch more than 1 minute of gambling content, then content with gambling keywords is found again on social media homepages, so you have to immediately filter content that is worth watching and it is better to filter gambling content if you are not the type of gambler.
