Small instance with about 3 users and myself online for about 2 weeks.

Absolutely.

As someone who owns their own instance, it is hard to get your instance recognized. You don’t have much content because of the lack of people, and it’s hard to get content if you don’t have people join. It’s a chicken and the egg scenario. Because of this some people choose to re-post content from Reddit to attract people over to their instance. It’s great to see the Lemmy community grow, but everyone joining a few huge Lemmy servers kind of defeats the purpose of the fediverse.

There could be a few reasons.

• They want to copy over their favorite content.
• They want to try to attract more people to a community by bootstrapping content.
• They are trying to artificially inflate their instance for nefarious reasons.

Personally, I think adding some of your favorite Reddit posts is fine as long as you don’t blindly copy over everything from a subreddit. I have a couple communities that I brought over that I like, but without content, they mean nothing.
