Try removing the "https://" if present in the address bar,
and if it's already absent try inserting it.
I've noticed in my GMail, if I type a link for someone and remove the "https://"
that the big automatic link picture disappears to leave only the link address itself, in blue,
underlined and active. Handy sometimes to minimise space and also to not
insert a big intrusive, premature title at the very top of YOUR text message.
The point is, changing a links text can change its method of operation.
If your State is censoring your content MAYBE a VPN MIGHT get round it by appearing to be somewhere else, tho' i'm guessing there.
Is there a HOT list, or blacklist or Whitelist ANYWHERE that contains Spankbang ?
also check any SafeSearch Settings ?
Your video posted here, and Spankbang in general, both working fine here in London.
Try contacting your internet service provider about State restriction ?
Try contacting support/moderator here, they're pretty good.
