thanks for filing! I'd definitely like to do this.

first, we have to figure out how to get or generate that like permalink. FB doesn't return it in the API call that creates the like. I'll keep looking, but let me know if you have any ideas!

Perhaps immediately make a call to check the user's "/allactivity" and grab the permalink from the most recent like post there? Possible race condition with other FB clients between the two calls, but unlikely. Can also double check the timestamp.

In case it helps - all the "NovemberProject's photo" like posts here http://tantek.com/2015/002/f now have a manually added syndication link to the FB POSSE copy of the like, for all them that didn't 404 (#331) error out when trying to Bridgy Publish the POSSE like to FB.

ongoing research:

• /USER_ID/likes returns a user's likes, but only of pages, not posts, and i don't see anything related to the permalinks
• http://stackoverflow.com/questions/9984051/facebook-api-retrieve-all-activity implies that /allactivity isn't available via the API. >2.5y old, but still

...tentative conclusion so far is that we don't know how to get the like permalinks. :/ deprioritizing for now, sadly.

...and closing altogether now that publish for facebook likes and comments is dead (#350). :(
