Use a libreddit mirror like https://reddit.adminforge.de to link to Reddit threads so that Reddit gets 0 traffic and 0 ad revenue from us opening the thread.

For example, if the Reddit link is:

https://old.reddit.com/r/aww/comments/14clza9/i_present_to_you_john_blobiver/

Then you simply have to replace old.reddit.com by reddit.adminforge.de so that the link becomes:

https://reddit.adminforge.de/r/aww/comments/14clza9/i_present_to_you_john_blobiver/
