I hate ads because they usually involve tracking.

I hate Facebook ads because a lot of them are for games, scams, BS products, or companies/politicians where the ad says "click like if you think/agree..." and the statement has almost nothing to do with that company/politician and are just using it to gain likes for the company/politician's Facebook page.

Before I started blocking ads and JavaScript, I've clicked on exactly four ads:

1 Google text ad in their search results - no sale

2 Facebook ads - I bought the products of both ads

1 ad on a blog (not using a third party ad service) - no sale
