If I "at" the original poster and posted a link to my existing thread like this ➡️ https://mastodon.social/@rameshgupta/113732127875416207, I'd be accused of #hijacking someone's post.
If instead, I "replied" to the original post ➡️ https://mastodon.online/@SocraticEthics/113731407465220573, and since I'm a guy, I'd be labeled #ReplyGuy because someone might consider that clarification "annoying."
Social media is fickle. Stop bothering about what people think and do what makes sense to you in good faith.
It's NOT humanly possible to earn EVERYBODY's adulation
