Tell me you don't know how a computer works without telling me you know how a computer works. That link is called a Mailto link, it is basically a hyperlink for your email client (If any) and will try to open said client to paste the To field in for you. It is not malicious, it does not open any backdoors, it is literally just a time saver for people who use mail clients. You can easily set it to a web browser to send that To: field to a web client like Yahoo or Gmail as well. Try to learn a feature that has been on the web for longer than you've likely been alive before you call it malicious immediately, will you?
As for your arguments... Search engines will have certain things they look for, one of which is popularity. You can clearly see you are looking for the most popular games with that tag in your own screenshot. Do you know how insanely big the furry fandom in general is? Do you know that for the most part they police themselves far harder than you would try to police them, because they don't like seeing people use the furry card as an excuse to do some vile things? Seriously, grow up. These games are not aimed at minors, any with actual sexual content will warn you it is 18+ only.
You aren't trying to protect independent game creation with this sorry excuse of an argument. You're looking at something you don't like, drawing conclusions with a lack of evidence and critical thinking, and immediately assuming the worst and trying to beat people over the head with your newfound logic. Not only that, you're making horrendously false assumptions. Most furries are straight? Have you seen the furry fandom? Clearly you haven't, it's got a massive swathe of people who are all over the LGBT+ spectrum, if anything I think straight people are in the minority. The games you're finding have bestiality? Doubt it, unless it's creatures you wouldn't find IRL like Dragons. Then again, that wouldn't fit the definition at that point - as bestiality doesn't apply to creatures that don't exist, including anthropomorphic versions of animals. The games are aimed at minors? As I said earlier, they are not, quit deluding yourself into thinking they are. A cartoonish look doesn't mean something is made for, or aimed at, minors.
If you truly do think you're in the right, step back and do some research and critical thinking. You're making a mountain out of a molehill, because if this truly was the problem you think it is it would have been shut down years ago. They are not pedophiliac, do not contain bestiality, they are not aimed at children, they are not unpoliced by either the site or their own community, and they are not made by minors. This is a hit piece on something you do not like, plain and simple. Take a step back and calm down before returning to this thread if you truly care - because right now you're blindly hating on this just because the furry fandom exists and you think its an issue, at least in my eyes.
