At first I thought this was Twitter b.s., but no I have been referred to the PayPal website update:
You may not use the PayPal service for activities that…involve the sending, posting, or publication of any messages, content, or materials that, in PayPal’s sole discretion, (a) are harmful, obscene, harassing, or objectionable, (b) depict or appear to depict nudity, sexual or other intimate activities, (c) depict or promote illegal drug use, (d) depict or promote violence, criminal activity, cruelty, or self-harm (e) depict, promote, or incite hatred or discrimination of protected groups or of individuals or groups based on protected characteristics (e.g. race, religion, gender or gender identity, sexual orientation, etc.) (f) present a risk to user safety or wellbeing, (g) are fraudulent, promote misinformation, or are unlawful, (h) infringe the privacy, intellectual property rights, or other proprietary rights of any party, or (i) are otherwise unfit for publication.
You can’t buy Traveler’s Checks (with PayPal) either! For each offense, at the discretion of PayPal: “Violation of this Acceptable Use Policy constitutes a violation of the PayPal User Agreement and may subject you to damages, including liquidated damages of $2,500.00 U.S. dollars per violation, which may be debited directly from your PayPal account(s) as outlined in the User Agreement…”
Update: The policy partially has been walked back, I don’t yet know the full details. And note that in 2018 PayPal was supporting net neutrality!
