discord 99
The act of leaving several forgotten group chats with intentions of clearing your DMs, at the expense of everyone else in which their DMs are drowned out by leave-notifications of the resurfaced group chats. This can cause a chain reaction in which by instinct, some users may start leaving the group chats to reverse the tidal wave of spam in their DMs, which only worsens the spam for the remaining users. It is considered one of the biggest middle fingers you could give over the platform, rivaled by the "Mr. Ping Challenge."
