September was an exciting month: less active websites but more spend with more comments posted.
The monthly price explains more credits spent on having an active API key in the system. In August, this pricing model was enabled only for half a month.
Some existing users decided to stop using JustComments, and the most frequent reason is that they could not justify paying $5/month for comments on a website with few visitors.
In September, 54 new accounts have were created, 7 were deleted. New accounts can try the system for a week or so for free, after that the account gets disabled if the user does not pay. So from those 54, 36 accounts have been disabled without payment so far. There is still a week during which the accounts created this week can become disabled so that the number could be higher than 36.
So this kind of conversion rate for new accounts is quite terrible, and I am not sure why they don't convert. Before you create an account, you know the pricing and how the system looks like, so there are very few things that could be surprising? I have not received a single line of feedback from those users, though. Probably, I have to reach out to them and ask for the feedback.
