Blog comment backlinks still effective?

Commenting on relevant posts still works

TO be honest with you, Still Working for me "relevant " and i ranked many sites with kws more than 100k search/month and everything works Perfect, But don't forget that , you should be careful and try to filter your list and choose only the good quality with Low OBL like Max = 10 and Good DR or DA or PA , regarding which metrics you work with,
also i'm not talking about auto approve Blog comment

While blog commenting is useless to build links, it can possibly lead to an increase in traffic to your website if properly used.

Anyone has experience in comments on medium blogs? Is it ok to get traffic?
