Say what you will about reddit, at least an established subreddit was the place to gather on the topic, ie r/technology etc.
With Lemmy, doesn’t it follow that similar communities on different instances will simply dilute the userbase, for example !technology@lemmy.ml and !technology@beehaw.org. How do we best use lemmy as a (small c) community when a topic can be split amongst many (large C) Communities?
This is an earnest question, in no way am I suggesting lemmy is inferior to reddit. I’m quite enjoying myself here.
I think this would reduce spam if anything. If someone does misuse it, then only one post needs to be reported as spam instead of every sub/com needing to deal with it individually.
Also, a user who is subbed to multiple coms, would only see the post once instead of multiple times.
And for actual spammers it’s never a problem to make a hundred identical posts anyway.
