I have problems with my partner. She keeps falling for these scams and it is so tedious explaining to her why I think something is a scam (usually various coach programmes, how to get wealthy and so on) and often times scammers use quite clever manipulation techniques, so that she believes them more than myself. She gets upset and say "everything is a scam to you!" and I say "no, it happens that you are being attracted to these kind of offers and so the Facebook / whatever algorithms keep pushing more of these at you". She goes "you just don't want me to succeed in life!" and so on. She even got to some (probably a cult) meeting telling her how she could invest her money without paying tax. When I told her that these things are illegal and not going to work, she says that I am just stupid and everyone does it. Then I showed her analysis of one of such schemes done by a reputable accountant, she says that it's just a smear campaign. It's so so exhausting. I wish advertising was more regulated. I am probably going to install some sort of ad blocking on the network level. Does anyone know about good PiHole tutorial? How can I hook it up to the router? I also been thinking about contacting Trading Standards, but I have a feeling they are not doing anything about it. Technically those scams are not illegal in the UK. Anyone can pretend to be an adviser and they can sell any sort of pie in the sky schemes without bearing any liability.
