Just got done investigating a spambot we had earlier, and it looks like they used a lot of compromised accounts on other instances to give their post an initial upvote boost. If you don't already, please remember to use a good strong password. Keeping your account secure helps reduce spam across the whole of lemmy, and keeps your account from getting banned for things you didn't actually do.
