UPDATE:

European Parliament approved new copyright rules for the internet:

www.europarl.europa.eu/news/en/press-room/20190321IPR32110/european-parliament-approves-new-copyright-rules-for-the-internet

How this affects on ipernity is supposedly and hopefully here:

(37a) "... The definition of an online content sharing service under this Directive ... does not include services which have another main purpose than enabling users to upload and share a large amount of copyright protected content with the purpose of obtaining profit from this activity ..."

The approved proposal available for example here:

My personal wish is that you all try to keep our web site clean out of copyright infringements anyway. To help you understand all possible dangers of infringing the copyright by accident, please start for example from here:

ADDITION

I guess people may easily misunderstand the new EU Copyright Directive's Article 11 (so called "link tax"). As far as I have found out, it only concerns the news media articles less than two year old. Using other citations and links to them is not covered there on Article 11. So, you are free to cite for example Wikipedia articles, which are anyway published under Creative Commons. The same is with for example short citations of song. You can still do that. But not the whole texts.

Moreover, my person guideline is that whenever I cite some text or give for example link to any content, I try to make sure the source is legal. And that is because I do not want to support someone else shamelessly infringing the copyright. So, links and citations on trusted sources is a good and recommended procedure.
