I've got the paths listed without quotes, like so:
binhex-plexpass/Plex Media Server/Crash Reports/,binhex-plexpass/Plex Media Server/Logs/,binhex-plexpass/Plex Media Server/Media/,binhex-plexpass/Plex Media Server/Metadata/
They get quoted during runtime so it works fine.
You can also do exclusions like:
.cache,.caches,.DS_Store,*.log,*.log.*,*.tmp,cache,Cache,caches,Caches,.Recycle.Bin
