You probably mean a PHP that can be hosted for cheap. But then, you end up with a Wordpress nightmare, even more spam and security issues.
I had a pretty popular blog and some posts gathered hundreds of useful comments. But I was so tired of fighting spam that I threw it all away and started using Hugo too, without comments.
In the 2010s if you left a wordpress blog unattended even with the official default filter plugin it would fill with spam comments. I dont know if thats still a problem.
