Yeah I can see why the ads are annoying & I'm actually a pretty big advocate for privacy. I recommend people to use ad block (uBlock Origin is best) & a good VPN like IVPN or Mullvad even tho I'm not sponsored by them.
In regards to the ads, the ad platform I use actually doesn't allow malware. They told me that if I find any to report it.
Issue is people make new accounts & they'll make an ad that goes to a normal website, then once the ad is approved they change the website to have malware & its pretty hard for the platform to keep up with banning these people.
The best defence is a good ad block & some common sense. But I try to make the warning on my website as visible as possible to help people not fall for it. I also stopped using & linkvertise because viewers hate it. So I try to be at least one of the better script YouTubers in that sense.
Contact them using Sir Memes Discord, they have some staff who can help you, you can also check out the Official Support Guide which has a lot of questions and answers
I used to use this thing called "GameGuardian" when I was exploiting on Mobile. It's not that bad, but JJSploit would be better that it since it's a PC Exploit but GG (GameGuardian) is for mobile. https://gameguardian.net/
If you're ridiculously concerned and don't want to buy a VPN or use TunnelBear for some reason you can always use Tallow to generate a temporary one for you.
