rbing again real quick--i and other(s?) have noted in other rbs that this is almost never done. it's for very few properties, and it's only for timestamped warnings that are done in-house, not by users.
there are still timestamps available for warnings on those same triggers for those same properties. just bc there's a paywall on something doesn't mean other comments and timestamps can't be posted or read for free on that property or that trigger.
i don't have an account and haven't paid for anything on the site, so all of those comments are what i'm seeing for free.
i had to search and search to find anything that had paywalls, and had to resort to looking at The Substance, as referenced here. i've been using the site regularly since the op posted and have never organically encountered a paywall on anything, including on very popular properties.
i don't see any reason to stop using the site--everything is still available for free. they just have added another way for some ppl to choose to pay some $ (in addition to ads), since this is a completely free service, and no website is free to maintain.
as an example, someone with the money could pay to see the timestamps, and then leave a free comment with the same timestamps for others if they wanted to.
