The report button is in the place where reply should be.
I'm a lefty and even I use my phone mostly with right thumb. Also it's very easy to report a comment without noticing (happened to me twice. Reported a perfectly legit and appropriate comment because of awkward report action placement.
IMHO opinion the report action should be placed anywhere else in the post but where it is now.

I agree overall. I think the motivation for placing the report button there was to actually encourage the use of it (social platforms like these slide down the shitter eventually with bad content). If I hit the report button, it will ask me for confirmation which is fine in my books.

Other than that, I think the reply button should be easier to hit. Make it bigger or maybe use some gestures.

There is a weird grey bar to the left of the ++/-- which appears to not have any purpose other than signify a response.

The social media buttons are just visual clutter to me.

The avatars, I like the customization, but I'm not so keen on the roundness. It kinda ruins the consistency for me.
