some of your are worried you'll be misclassified as bots.

which tells me you don't really know what moxie farmer bots look like.

moxie farmer bots saturate cast replies with mechanical content, such as below.

the markers:
>casts too regularly (every five minutes, every hour, for 24+ hours)
>casts are too regular (length, verbosity, emoji usage all drift together)
>casts too often (wake casts 1000 times/ week; this user casts 1000/day)
>is very poorly integrated (not followed by credible users)

Good example of replying to every cast with a low effort reply even if positive / well-intentioned. It's fine to do occasionally. 

Doing this at-scale is farming and spammy.

Believe it or not, sometimes just liking a cast is enough to show your support. Replying to it all is a little excessive. Even to legit friends you engage with everyday.
