Change Log:
2.23 (05-Nov-2024) - Update by ".Rushaway"

- Now less checks of GetClientAuthId by storing them.
- Switch to Steam3 format for AuthID.
- Fixed g_smWaiting not removing data for unverified clients.
- Prevent g_smWaiting not removing data if client was already disconnected.
- LogAction now print infos even if client is not verified.
2.22 (28-Jan-2024)
- Fixed memory leak caused by clearing StringMap/ArrayList data instead of deleting.
2.21 (19-Feb-2023)
- Now prevents even more log spamming duplicate entries. Thanks to ".Rushaway" for reporting.
2.20 (20-Jan-2023)
- Now logs if a Steam ID is unverified.
- Now prevents log spamming duplicate entries.
- Fixed checking bots for sprays.
- Thanks to ".Rushaway" for reporting and help testing.

- Fixed invalid handle errors. Thanks to "nikooo777" for reporting.
2.18 (24-Dec-2022)
- Changed moving sprays to use an asynchronous method to prevent a script execution timed out error. Thanks to ".Rushaway" for reporting.
2.17 (08-Oct-2022)
- Fixed command "sm_spray_test" getting stuck processing under certain conditions.
- Re-wrote the recursive directory function to avoid several bugs under several conditions.
- Now only moves sprays (.dat or .dat.ztmp) and not other files to the "backup_sprays" folder.
- Now deletes empty directories on plugin start after moving sprays to the "backup_sprays" folder.
2.16 (30-Sep-2022)

- Fixed client not in game errors when renaming sprays.
- Now moves "dat.ztmp" spray files to backup folder.
2.15 (22-Sep-2022)
- Fixed not deleting the old backup if the names match.
2.14 (22-Sep-2022)
- Added cvar "spray_exploit_fixer_msg" to control if messages should print to the server console. Requested by ".Rushaway".
- Plugin now moves all sprays to the "download/backup_sprays" folder on plugin start and client disconnect.
- Removed saving checked and blocked sprays to file. All sprays will be checked.

2.7 (08-Mar-2022)
- Added support for banning using the "Material Admin" plugin. Thanks to "lechuga" for adding.
2.6 (01-Mar-2022)
- Another crash exploit fixed. Thanks to Kenzzer for reporting.
2.5 (15-Jan-2022)
- Fixed randomly using recursive folder and extension names in spray filenames causing validation failure. Thanks to "A1m" for reporting.
2.4 (02-Dec-2021)

1.3 (26-Apr-2020)
- Changed cvar "spray_exploit_fixer_log" to log all files or only invalid sprays.
- Logging now saves to "sourcemod/logs/spray_downloads.log" file.
1.2 (23-Apr-2020)
- Added better checks to detect more bad sprays.
- Added better checks for TF2 and other games to avoid false positives.
- Prevented banning people in TF2 since many random invalid files are sent, not just sprays.

- Added ability to detect the users uploading sprays or other files.
- Added cvar "spray_exploit_fixer_ban" to ban players with invalid sprays.
