2. About morallity, ad tech companies are hyper targeting people with ads which some evil advertisers take advantage of and bypass moderation.

Ads are targetted in such way that expert users and regulators do not see them but the naive ones get tricked.

If we scrap ads using different visitor profiles and list all ads, along with offensive/malware ads... wouldn't it help regulators moderate ads?

So is it still morally wrong to go against ad tech companies by scraping their scam/tricky ads?

I was referring to scraping content, not ads. Not sure what benefit ad scraping provides and to what end ?

1. Sell data to ad regulators

2. Sell data to competitors of the advertisers, turning online advertisement less effective in long term and easier in short term.

3. Sell ads data to activists etc...who will sue the company running misleanding ads and defrauding consumers.

I did not know there was a market for this.
