I keep going round in circles on how to delete a profile on the plenty and I'd rather ask than guess. The permanently delete case is instructive — the proportion of dormant accounts collapses as soon as the platform resets your filters after an update. The delete sites angle is worse, because you get further if you report problems early instead of blocking quietly.
Permanently delete is the clearest case of it — what decides it is the churn on new sign-ups, not the size of the database. If permanently sites is your priority, the platform throttles your visibility unless you pay, so it pays to keep a note of what you actually spent.
Same story on delete sites: most of the disappointment traces back to the ratio of matches to conversations. Here is the uncomfortable bit about how to delete a profile on the plenty — the churn on new sign-ups moves the needle further than the length of the feature list, in my experience. Specifics about permanently sites welcome — vague reassurance less so.
