The point is not what you posted or why. The point is that you posted the same content twice, thereby drawing from the steem (and token) reward pool twice.

3speak is not a different platform, what you post on 3speak, gets posted on the steem blockchain (automatically as far as I know). So, the post appears on your feed on steemit and the other front-ends, as well as any tagged tribes' front-ends.

Let me put it this way; if you had a photography blog, and had uploaded a photography to facebook, instagram, twitter, imgur, pinterest and deviantart, would you then make six different posts on six different front-ends on the steem blockchain to showcase your photo...?

All of this is not "my point of view", recycling content is a known form of abuse which the steemcleaners deal with on a daily basis. It's a growing problem among artists on the steem platform, because many of the artists and content creators lack understanding of how steem works, or what gets posted where.

I must say, I'm very surprised that you, being a musician, are not aware of the general views on recycling content or how the steem blockchain front-ends work.
