What are the statistics and figures that can be used to convince some friends of the necessity of controlling internet usage in homes in countries where pornography is legal, especially given the lack of control over children's devices?

The Prophet, peace and blessings be upon him, mentioned that among the signs of the Hour is the prevalence of zina (unlawful sexual intercourse). The internet has indeed brought this to light with the proliferation of pornographic websites, whose number has exceeded half a million and is increasing daily, confirming what the Prophet foretold. The percentage of pornographic pages is estimated at 2.3% of the total internet pages, and millions visit these sites weekly. Sales of pornography materials on the internet are estimated in billions of dollars. Studies have found that half of the images retrieved from the internet are pornographic. Therefore, whoever leaves the internet available to his family and children without blocking evil is sinful and a betrayer of trust.
