High CPU Usage for the last few days (steemyy.com)

I have observed High CPU usage for site steemyy.com in the last few days.

This is a 4 cores (2.4GHz Intel Xeon CPU E5-2680), 6G RAM VPS.

The normal load should be less than 4. But it is staying abnormally higher than 4 for a longer period of time.

I also received notification of emails:

The process php-fpm is responsible for handling the PHP scripts, and thus most likely it is the website traffic. I checked the traffic, not seeing much unusual activities apart from search bots crawling.

The server is behind CloudFlare, and I do have a few rules to block the naughty IPs.

I also have a rate-limit rule for the Proxy Node at endpoint /node

I will closely monitor this.
