Aimco suing Airbnb in 2 states

"No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” 47 U.S.C. § 230(c)

Notably, “section 230(c)(1) precludes liability that treats a website as the publisher or speaker of information users provide on the website.”4 Doe v. Internet Brands, Inc.
, 824 F.3d 846, 850 (9th Cir. 2016).

Immunity is not foreclosed simply because a website offers more than a “bulletin board” service, or an online site “on which Internet subscribers post comments and respond to comments posted by others.”Kimzey , 836 F.3d at 1266 (quoting FTC v. Accusearch Inc. , 570 F.3d 1187, 1195 (10th Cir. 2009));
see, e.g.
,
Carafano v. Metrosplash.com. Inc.
, 339 F.3d 1119, 1124 (9th Cir. 2003) (“So long as a third party willingly provides the essential published content, the interactive service provider receives full immunity regardless of the specific editing or selection process.”).

Accordingly, requiring prospective hosts to include information such as home type, room type, location, description, name, email address, and phone number when creating listings does not “materially contribute to the alleged unlawfulness of the listings.

Similarly, offering ancillary services such as user information verification, messaging systems, photography, local occupancy tax collection and remittance, a pricing tool, host insurance, a guest refund policy, or an autocomplete search function does not materially contribute to the alleged unlawfulness.
