One more simple solution for using any search provider is using adblockers, something like uBlock origin for example, and they will block most ads including scam website.
I might be wrong on this one, but I don't think that uBlock Origin[1] is enough to warrant protection from phishing websites. All the more I would say that we shouldn't let our guard down just because we're using uBlock Origin - or any other protective measure - as we may be still prone to attack vectors. As an example, I'm a user of uBlock Origin and here's the results I get when I'm search for "chipmixer" using Google (Firefox Browser):
What's even worse is that is the only result I get whenever I search for it (in the corner you'll see I'm using uBlock Origin) is a phising website! I gotta say that I'm surprised - I was hoping to find at least the real address on the first page but that wasn't the case. Again, I'm not saying that uBlock is useless - I can't imagine myself browsing the internet without it - but I just don't believe it should warrant any feeling of increased security regarding this type of scams.
So, I started with tor, then connected to it through vpn, sent BTC from an ATM with a burner phone straight to chipmixer (first service I researched) and then imported the keys into an electrum wallet on a vps.
If you are using Tor, then you don't need to use a VPN unless you have a very specific reason to. Additionally, if you import the keys from ChipMixer (the real one!) to your Electrum wallet, then be aware that ChipMixer will still know your keys. Better for your security is to sweep the coins from the ChipMixer addresses to your Electrum wallet, but be aware that if you deposit x coins to ChipMixer and then immediately withdraw the same amount of coins from ChipMixer then it potentially weakens your privacy.
I gotta say, if this was your first few times in this "waters" I'm baffled with the amount of security layers that you've employed - ranging from using TOR with a VPN + ATM + Burner Phone + VPS. You did really went all in with these methods!
To complement what o_e_l_e_o said, if you want to have additional privacy while using Chipmixer I would advise you to let your coins there for a couple of days before using them - that way you are increasing the "entropy" - if we may call it that - of your mixing process.
Bisq and LocalCryptos are the two most commonly recommended and widely used non-KYC peer-to-peer exchanges.
