If you want to go further:
Maltiez actually went to Anego and suggested an "anticheat". Ultimately this was not feasable for Anego and it was up to server hosts to manage their servers, whitelist, ban bad actors, etc. Then Maltiez added a malware to their mods after being told no. According to Maltiez themself, the malware was successful and the cheat mod maker had given up and discontinued their mod.
So then why keep the malware in? Why create a blacklist after other modmakers contacted Maltiez after figuring out their mods were causing issues instead of removing the malware?
Then Maltiez started doubling down and justifying themself. There is a reason vigilante behavior is not good, because ultimately taking down the "bad guys" became more important that protecting the victims
