Dear op, I also had the same query but, I never wasted my time on it again, as I also thought, maybe that tab is not for the users of BTT, while maybe for the Admins or for moderators. But now after reading all the replies I can say, we don't need that, and Theymos has already said the reason was cost (MusaMohamed said in the above reply of his). Well, if the cost was high then why current stats page is enabled?
And just to point out, I think the current Stats page, also has technical errors, as shahzadafzal discussed here:
There was a massive DDOS in 2017 and things got a little better after Moving to Cloudflare.
Don't you think that's becoming often this day with BTT site going offline more rapidly?
Well, that massive DDOS attack of 2017 was also similar to the recent unavailability of BTT. Like BTT going down, did the same thing happen in 2017 or what? Actually, I heard about it for the first time, so I thought I should ask if you are willing to tell the story.
