Make it five. I nuked 12, 8, and 5 year old accounts. In all three I had comments that used to be linked in Google search results. I put up with a lot from Reddit admin over the years, but it just simply wasn't worth it anymore, and fuck them, they're not gonna reap the benefits from Google traffic on my old accounts. I scrubbed and deleted my Twitter account a couple days ago as well. I'm sick and tired of these rich, stupid clownshoes ruining everything. This fediverse stuff is legit. I'm genuinely invested in seeing decentralized social media succeed.
Sure, Reddit and Twitter aren't going to collapse because some power users killed their accounts, but Lemmy and Mastadon can grow and show that what they're doing works if myself and others are making an effort to participate.
