Website DDOS through tor network

OK, where do you get those stats (O visitors, 1GB)?
Does this come from analysis of the server logs?

Unless you are a brand new site you should be getting hammered by all those bots and scrapers and hacking attempts for vulnerable software like Wordpress and all those other CMS types. In this hammering I include legit traffic like Google, Bing, Yahoo, Yandex, Apple, etc etc etc.

Agreed 1GB is not a lot unless it is within 1 or 2 seconds.

I also don’t get this:

Today a new ip was added to the list and immediately I got traffic from that ip.

I presume this means to the blocklist; so how does adding an IP to a blocklist get you traffic from it.

The website had a leak on the former hoster, that is why the website was rebuild and there are no leaks now. What can I do or what should I do?

Rebuilt on a new hoster, I presume, like what software (not the hoster). Maybe the framework has some vulnerability and it is getting exploited.

Lastly, are those stats you state only for Tor traffic and I am reading this post wrong.

Most site get tons of traffic and I estimate 50% or more is scraping (junk).
