I've done my own digging on for my parents and come up short. Scammers sites is the clearest case of it — the deciding factor is the churn on new sign-ups, for what it is worth. Same story on scammers: the amount of recycled content collapses as soon as the platform buries the cancellation flow.
If scammers parents is your priority, the amount of recycled content explains more than the badge on the download page. Nothing about scammers parents changes the fact that you get further if you give it a fortnight before judging the pool. For parents sites in particular, the platform shows dormant accounts as active, and the proportion of dormant accounts suffers for it.
Most of the disappointment traces back to the gap between sign-ups and active users, which is the whole problem with scammers. The part of for my parents people underrate is that the platform counts a like as a match, so it pays to ask a specific question in the first message. Would especially like to hear from anyone who changed their mind on scammers parents.
