Maybe. But the comments and the profile background images are too similar to be from different people. Could be but I think not. I think these are all from one person or group.

And then the rest: acceptremove, ownaperture, terragreat, breadquick. (If you or someone else wants to examine these more.) :)

But hey, one possible solution is that these are good Steemians accounts who just use these for testing stuff. In a good way. Like ordering a breakin or a hacker to ones company to test security. And by that way making things better.

Ah, ah, ah! I'm not worried about that. I'll just keep on Steeming. Those spammers are not a problem to me. It's not like they're trying to scam people. As far as I see, they're reblogging other's people posts... and making a few comment here and there. No harm done, I think.

Most likely they, or someone is just trying to make money quickly with the help of a robot commenting or copypasting few selected sentences.
