"403 Forbidden" when it's scrapping Buffer App's shorturl

[remagio]

It happens with earls.js and load.js, results are:

• The earls webpage list correctly the URL but with title "403 Forbidden"
• Counting are ok, the link works fine and Twitter's user list too

imho I think Buffer is blocking only when it try to scrape the document's title

All urls get same description inside earls log, including when happen quotes/retweets:

Seems to work now after the HTTP request has a common User-Agent:
