social media address normalisation

Hi! Please see the note at m:talk:Reasonator#P554. A bot should remove all superfluous "pages/..." prefixes. The Facebook pagenames are not permanent, they can change at any time. Regards GangLeri לערי ריינהארט (talk) 09:01, 22 May 2014 (UTC)

@Ivan_A._Krestinin Please note the change at https://www.wikidata.org/?diff=132254398&oldid=132249961#top . The following urls are equivalent:

• https://www.facebook.com/pages/Friends-of-Unicode/127785250588285
• only 127785250588285 at https://www.facebook.com/127785250588285

Question: Can you please "watch" this topic? At some point in time the values can be "normalized". Regards gangLeri לערי ריינהארט (talk) 10:00, 22 May 2014 (UTC)
