A few things:
1. Requirements of spiking/lagging:
If the report is based on clanwar you have to provide a replay with minimum of 3 rounds and minimum of 4 screenshots showing the ping of the user.
If the report is based on any other game-mode you have to provide a replay with minimum of 6 rounds and minimum of 4 screenshots showing the ping of the user.
You have provided a 3 rounds replay which isn't enough evidence.
2. I remember you've made a report around a month ago about someone who was spiking in a 1v1 and I personally wrote this: "it's a 1v1 so it is impossible to know whether it was you or him (when you lag/spike, everyone else is lagging in the replay as well but there was only 1 person in the room)."
3. His ping was kinda stable in the replay but I've noticed a few glitchy movements in the second round, still not enough for a punishment since it wasn't a long replay.
