Hi
I actually do not delete comment spam.
The way I work is simple. I look for posts that are related to subject that Im interested with. For instance: crypto effect.ai
I will find several posts and read most of it and close those posts that I dont enjoy. I then write one message that could fit anyone interested with this project and copy paste it several times. And Im doing my best to change those messages almost every day.
This way I never ever leave unrelated comments. On top of that I reply and I follow + I use my upvoting power to upvote interesting content of those people.
Anyway if you disagree with my methods then I dont think Im capable of convincing you.
My goal is to get to know interesting and responsive people. Just like you. People from this industry. As I believe allowing to get to know right people would be the most important thing that steemit.
Anyway thx for your comment. I appreciate. Really
