Since last 7 days, there is a considerable increase in CPU usage. This makes this website not available sometimes. You may have seen spambots registering on this site. But it is not the one causing this problem, there are some processes running continuously on one of my websites.
But I also like to reduce the number of spambots registering on this website. So, I thought blocking visits from China, Russia and Ukraine will be a good option. Since most of the spambots are from there. So, I went to the website - https://www.ip2location.com/blockvisitorsbycountry.aspx
On the website, a person can generate a code which blocks visits by country.
The last option should be Apache 2.0 - 2.3 .htaccess deny
But I forgot to change it and left the default option - Apache 2.0 - 2.3 .htaccess allow
I downloaded the code and added it to the website's .htaccess file and I slept.
What the code did was, it allowed visits from China, Russia, Ukraine, and blocked all other countries.
Spambots are the computer programs which are used to register accounts on various websites to post spam links, grab Email links for marketing, or for other similar purposes.

Now I changed the code to the right code.
Who are the spambots? Spambots ruined Blurtit.

@Dan: Thank you for answering my question. I thought maybe you were working on it again!
That is interesting, Dan - I can see that maintaining a website takes much time and work!
I notice sometimes that this website is down.
Yes, Rooster, I got also an error warning, this time 103 (usually, it is 104).
Luckily, Dan could settle the problem - thank you, Dan.
P.S.
Oops, I should have written 403 and 404. Lol.
I got a 403 error: "Forbidden You don't have permission to access / on this server."
Lol, yes, T(h)ink, I made a mistake; it was a 403 (or 404) error ...

Oh, thank you, Dan.
This list is useful.
