A post on Reddit gave advance warning of a ban wave that would hit Tom Clancy's Rainbow Six Siege today for players who were using a chat symbol to deliberately crash multiplayer games in the military shooter (thanks PCGamesN). Word is: "These bans are targeting players that abused the chat symbol exploit to crash matches. They will have varying lengths, depending on the frequency and severity of the exploit's usage. This is our next step towards sanctioning players that knowingly and deliberately take advantage of exploits to the detriment of the overall match." The banhammer obviously came down as promised, as this post describes seeing 200 players banned in under a minute and this one shows a wave of bans during a pro league broadcast.
