Is it just me or does it feel like the major tech companies have completely lost the war against bots/spam? Search results are regressing across multiple online services[1] - Google, Amazon, and app stores are all filled with junk and scams. Reviews for products are generally filled to the brim with bots or paid reviews. [1] I've noticed the re-emergence of Experts Exchange style sites on Google recently. For technical questions Stack Overflow or official docs are often near the bottom of the first page, while sites like w3schools or geeksforgeeks are at the top with much less useful content.
