Hi Dmitriy,

Thanks for getting in touch.

The reason we deleted your profile is because a number of our members reported your content as inappropriate for a professional network like The Dots - we really value our members feedback when it comes to assessing what is and isn’t appropriate content to promoted on our platform.

Rather than using The Dots, we’d recommend using social networks that have a broader scope, such as Twitter or Facebook :-)

All the best with everything.

Robyn & The Dots Team
