There is a question, how do I post a motorcycle with a sidecar and not get banned?

The situation is this, six months ago I posted a motorcycle mod with a sidecar...and got banned, with the phrase "in cooperation with foch_sho" (whatever that means)

Now that the ban term is over, how do I (or foch_sho) post the motorcycle so that we don't get banned?

The mod originally used veh from the motorcycle with sidecar mod, but we made everything from scratch after the author complained. Now everything in the mod is completely original, including the 3d model.

You simply submit the mod.
As with any original work you also submit some proof how you created the 3D model.
(for example timelapse video or screenshots that show the model and your reference photos etc)

Okay, I hope I don't get banned for a year )
