I value my attention. I don't spent it on artificially generated responses. If someone wants to communicate with me I insist they put in some minimum level of effort. Before email, it took work to write a letter, which helped weed out low signal-to-noise communiques. Messages the likes of spam, LLM-generated content, and reactions go straight to my trash folder. I do view it as disrespectful (more precisely, lacking discretion) that the sender decided to waste my time by making me look at and hit delete on their message.
It may sound aloof, but I sometimes get hundreds of emails a day and it's a necessary filter.
