More specifically, the DMCA provides that website operators are immune from copyright infringement if:

(a) they dont have actual knowledge of the infringing material on their services,

(b) don't receive a financial benefit directly attributable to the infringing material; and

(c) implement and comply with a notice and takedown procedure.

To implement and follow a notice and takedown procedure, the website operator must:

(1) designate a Copyright Agent to receive infringement claims (you can do that here);

(2) create a DMCA Policy and provide it to the site's users; and

(3) comply with your DMCA Policy if you receive an infringement claim (including potentially removing repeat offenders from your service).
