I know probably not the perfect place to post this but want to get the discussion started and don’t know enough to be scared or not: because of the decentralization of Lemmy, is it extremely vulnerable to malicious/ad bots, astroturfing, spam and such?
You created an account on the lemmy.world instance, but there are a ton of other instances out there.
Defederation explanation as far as I understand the topic: By default all instances talk with each other and publish their communities (The federation part). But if an instance decides to defederate from another, it will block the second instance from getting interacting with communities on the first instance. So the users of instance 2 can’t post on instance 1.
Do you think instance spamming could theoretically become an issue? I’m sure there will just be instance filters that instances can apply broadly though, like ad filter lists.
