I block every person on social media who contacts me about their service. If we run in the same online circle, I know the services you provide. It's your job to add value to the community and let your work speak for itself, not message me about about hiring you. If I need the service you provide I will contact you.
For instance, I'm a ghostwriter and run a hip-hop website. A lot of graphic designers hit me up, pitching album covers and other graphics. Blocked! Now on the other hand, if I see a graphic designer who does great work, I might hit them up "ON MY OWN" if a client of mine needs work done.
Put your work out there for the world to see, don't knock on my door asking me to buy something. Weird!
