At the top menu bar there should be Create Community button or you can go to the direct link. If you don’t see it then you instance has probably disabled the functionality.

It depends on the different clients as most of them started developemnt just weeks ago, but all most popular ones support moderating actions. But Lemmy lacks some hardcore/automatic moderation tools at the moment.

My advice would be to not wait for someone else to create communities would like to see, but create them yourself and just start posting. If you are not interested in moderating I’m sure you will be able to find someone else to take over.

You can post them in !newcommunities@lemmy.world to get some attention, but like minded people will find you.

Reddit a was shithole to be honest. Recreating it shouldn’t be the goal. Making something better should be the goal.

I have mixed feelings towards the repost bots. I see no value in pure reposts from Reddit, but I also have no issue with them IF they only post on dedicated instances and mark the account it’s posting from as a bot. Those posts have no engagement. Most people either disable bot posts in settings or block then once they see them. There is nothing wrong with growing communities slowly, but with organic content or only reposting the most interesting stuff.

Less of a problem on Lemmy where karma is not publically displayed.

Twitter is already struggling with For You being hardcore porn every 10th post. Not everyone wants that so they are bleeding that “huge amount of people”.
