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

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

News [email protected]

Memes and other bullshit [email protected]

"Math" [email protected]

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?
