What are the positives/Negatives of sv_download 1 and upload?

I was just curious as I want to enable sprays onto our server. Is there anything negative that could happen by enabling this? They are currently both set to 0

sv_allowdownload should be set to 0 if you are using FastDL or workshop to download content. sv_allowupload has been used in the past for server.cfg exploits, but I’m not sure if those are still present. Regardless, Source sprays can be inconsistent when networking to players, so it’d be best to use a Lua spray addon.

Thanks! I never knew lua spray addons were a thing.
