Yeah, I don't want to take action either but if it goes over a month then I guess I'll have to.
Good luck getting the replays again, if you deleted the entirety of csgo then the .dem files are gone too (they're usually stored in C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\replays\match730_bunch-of-numbers.dem). No point in re-downloading csgo, demo download availability last less than a week, then they are permanently deleted from their servers.
Luckily I still had all the .dem files on my PC, here's the MF link (if this isn't allowed then I guess I'll upload it to MPGH? lol);

It's heavily compressed (~50%) and also has the matches sorted into seperate folders, ordered by first played = 1, last played = 4. Even includes the .info files.
