Your profile will appear on these sites only if you've interacted with them directly (followed, created a project), or indirectly through projects (commented, respected). 

Moreover, only your interactions relevant to that platform will show. So for instance, if you've created a Particle project, and have commented on one Arduino project, then your profile on Hackster.io will show both your Particle project and your Arduino comment. However, only your Particle project will show on your profile on Particle's Hackster gallery, not your Arduino comment.
