is it ok to use accounts in place of multi-r*edits?

I miss multireddits, a workaround I found is to create accounts on different instances and subscribe to different communities with each account ie

News trabic@lemmy.world

Memes and other bullshit trabic@lemmy.one

"Math" trabic@lemmynsfw.com

Then just login to which ever one I'm looking to browse. I don't think this will screw with the fabric of the fediverse, is there any reason I shouldn't?
