Use an alternative chromium based browser?

Rule of thumb? You can’t. There is always a risk of malware. Best is to up your computer security with a good set of antivirus, antimalware and a VPN.

Get a VPN. Don’t use public wifi without a vpn. Using public wifi without a VPN is like having sex with random hookups without a condom.

Another alternative would be to download your anime of choice before hand and keep it on your device to watch. You could even store it on say google drive or something as they don’t pay much attention to the content of videos unless you upload them to youtube. If you need to you can pay the $30 a year and get the cheap premium package for 0.1TB Which isn’t that bad all things considered if you just use it to store files in transit.

I guess that means they don’t have an XBox or play a lot of PC games? Maybe they prefer Nintendo or PlayStation?

I don’t think it’s the amount but rather the context given the character development. If the character is always ecchi then it makes more sense. If you have a random sex scene then it doesn’t quite make sense. That’s true whether it’s anime or a romance novel. In fact anime is often compared to literature, as opposed to other visual media like television because of it’s advanced character development. I’ve got no problem with tons of fan service but I agree it has to be paired with good writing. I don’t find excessive amounts of Plot bad so much as badly written story and plot, now that’s cringe. So in essence I would disagree with the assertion that everyone hates fanservice but add the caveat that randomly throwing in a sex scene does not automatically improve things on its own either.
