That's not true, i only send 1 message to every chat, this is not a chat spammer,
A chat spammer would be sending 10 messages, on 1 chat.
Also my delay 250 ms is bigger than the delay they track (200ms or lower)
Also, sending a individual key and sleep doesn't make any difference than sending the raw text and then bigger sleep, they don't track individual key presses, only the time between messages send.
Ofc you could get potentialy banned(Or Silenced) if you keeping pressing [F6], but only pressing 1 time, is no way spamming trade chat.
