C-tapping with shotgun and deagle was allowed back then and still is, your infraction came from abusing its fire rate. I won't be removing the infraction nor lowering it, since your infraction history only consists of bug-exploits. Mentioning that, 3 days prior the infraction, you skipped sniper animation, which you were infracted for, therefor the 4 points are well applied, because you broke 2 same category rule in short period of time.
I'm done with you here and any higher ranking staff may take over it.
