In that case the issue is that it's user generated content. Just as you'd cite the references listed after a Wikipedia article for the source of that information rather than Wikipedia itself, Wikipedia policy favors references to established publications over those compiled by users in a manner similar to Wikipedia itself.
For the information to be verifiable, its original source has to be both clear and reputable.
We really need users like that on Lemmy to replicate the positive aspects of the Reddit community that are worth bringing over. Something original to here, hopefully.
