Here's the wiki page. My recommendation is that you first go through section labelled "introductory material" before moving on to anything else since it will provide a solid base for further research. The "reading list" section in particular will provide the most amount of high quality information for those interested in in-depth research while the "news sources" section will help you keep up to date.

r/Tigray is the only subreddit on Reddit centered on Tigray from the pov of Tigrayans. The Tigray genocide was successfully hidden from the world due to both the regular contempt African tragedies are shown and the successful disinformation campaign (+ the blockade) waged by the neoliberal UAE backed Ethiopia together with many of its diaspora that presented the victim as the aggressor and the neoliberal regime as the anti-imperialist. For more on the West's role in everything, read this post here.

As an important sidenote, this post, the resources and the subreddit are not in blind defence of the TPLF but are instead about bringing awareness to Tigray's situation. The TPLF indeed have a muddy history (1, 2, 3) of their own and a minority of the resistance against the genocide did indeed commit war crimes (1) but this doesn't justify the Tigray genocide nor the undermining of its plight. They've also played a secondary role in Tigray's suffering by how they've responded to the conditions Abiy's placed on them as explained here which is why support toward them has dropped but this hasn't translated to support toward Abiy since most Tegaru correctly recognize that he's at the root of their problems. Many Tegaru also still support the resistance just while recognizing the fault of the TPLF and the next several months will show how much they have left. More here.

Often times, the West use the double standard "perfect victim" strategy which employs "bothsidism" in order to undermine tragedies they'd prefer to ignore or even outright support especially non-Western ones. Beyond Tigray and with much global awareness, you can see this when it comes to Palestine and Sudan.

Please consider reading through those resources on the wiki and spreading awareness where you can. Tigray hasn't recovered from the genocide plus 1/3 of its land has remained occupied and now all of it's towns and cities are under occupation once more and the people are beyond exhausted from everything they've had to endure.
