Apparently a day or two ago, there were interstitial ads appearing as links to words in the text on the FAQ pages and elsewhere besides the main page. This happened as an error, and I did not know anything about it until a reader alerted me (Thanks FedUp). It’s not my intention to have hidden ads in the text, or indeed, to advertise for gambling and other non-related industries. You shouldn’t see any more of that. My apologies for any inconvenience or annoyance.
