Use your favourite search engine, search “<yourquerykeywords> reddit”. Whatever search results pop up, those threads should be old enough to be archived over at Internet Archive or archive.is. Install Resurrect Pages addon in web browser. Open your reddit search results, and Resurrect Pages gives you the option to open their archived versions. If the “reddit.com/…” archive cannot be found, scroll to an older version if available. You can also modify URL to “old.reddit.com/…” to see if archived version exists.
You can find more or less any relevant threads if you use a combination of Google, Bing and Yandex with that search-fu. You can also use Searx, Baidu, Startpage or any other search engine for this trick.
