Thank you for taking the time to make this report. I joined the server to see if i could see the logs of the round where this happened but sadly i was unable to find them and unfortunatly as soon as i joined both you and david left so i cant get evidence of the steamid either. As for what i can see he is allowed to call sus on whoever he likes, calling false suspicion is not a rulebreak. You have proof that Stephen threw an incend but there could have been valid reasons for him throwing it, there is also nothing to prove if you did or did not also throw an incend as i cant see the full logs.
When you are making a report on the forums it is vital that you provide all the information you can, most importantly the full logs and if the case requires it the shot logs of the round where the incident took place. It is also really important that you grab proof of the players steamid by either screenshotting it when they leave or typing status into the console to screenshot it there. Without proof of steamid we cannot verify the steamid leads to the right person.
As there is not enough evidence i will be denying this report, please make sure you provide more evidence in future reports.
