The main reason the bot communities were forbidden in lemm.ee was that they caused too much noise on the local feed, and people complained about it.

That's the one reason I can see it be an issue on any instance except a dedicated bot one.
The total number of posts would be a problem for us as the number of posts across all our communities would be in the low double digits. This is why we have a ** 5 posts per day, per community, per user ** rule.

Tentatively I think we can handle the polls community and your Zeitgeist community as I wouldn't foresee the posts going haywire for them.
But the sharegpt and Lemmy Issues communities, I foresee going haywire or so.

In saying that, as long as they all follow the instance rules, are well moderated, all communities are welcome (not just the ones listed here).
If you think they will be 5 or less posts per day then feel free to create them. If you could also spread out the posts so they don't just spam all at once, that would be amazing.
But if you think it's going to spam more than 5 posts per day then at this time I don't think the community will be a good fit for Reddthat.

At the end of the day we want communities to provide benefits to all our users, with content that is interesting/thoughtful/enjoyable/etc. That is something that should be considered before creating the communities.
And as always, if users don't wish to view the communities, they can always block them themselves.

Cheers,
