I allow them for a very small and selective number of sites that I mostly trust. For me this is a pretty high bar. I have three sites whitelisted right now. Conditions to be whitelisted: 1) I have been using your site for years. 2) Your site has timely important information in my specific field of interest. 3) Your site doesn't engage in monetization practices that lead to a poor user experience (ads that pop over or otherwise interrupt the articles, self-playing audio, self-resizing ads, begging for account creation, etc.) 4) Of all the existing sites on this topic, yours needs to be the best one (proven with many years track record). Has your site been around for many years? 99.99% of the time I would deny them and consider even the request to be a rude annoyance. If your site is not in the top 1% of long-established quality sites, you shouldn't even request the permission imho.
