I am having the same problems, is the plugin called EWWW Image Optimizer causing the high usage of CPU?

I am using siteground too, but still like @alicebertoni, facing bad bots unfortunately, but no idea how to solve it. May you also kindly help me to give suggestions?
@xprt007
Thanks for your sharing.
I have tried to limited them too, and I also installed a plugin called Blackhole Bots too! But seem the problem is remain.
The instant log sheet from Wordefence shows that most of the bots are browsing some links, like hash tag links, special images and so on.
I have no idea to block them, so see if any expert can help me?
