Starting lemmy server - which hardware to get? Dedi? ram? cpu?

Hey guys. Im trying to fully move to lemmy.Unfortunately many subreddits I was using - are not represented on lemmy. So I figured I would just sync content from reddit for those communities - so I scripted auto-reposter of top most popular reddit posts to lemmy.

but. im running into issues.

Lemmy communities that sometimes 0 content with last content sometimes posted 2 years ago - they ban me for "spam" when I auto post content even if their lemmy communities literally have no content...

This community just banned me, last post in that community was 2 years ago:https://lemmy.ml/c/buildapcsales

What are they even moderating?I cannot make this shit up.

Anyways - I would rather do my own server then deal with mods worse than on reddit that actually allows that.

Starting lemmy server - which hardware to get? Dedi? ram? cpu?What does lemmy.world uses? Thank you.
