I am suggesting to allow players to do the same command twice in a row, this is very annoying when doing /fix or /is. The ability to say the same thing twice should still not be allowed.
Support. Saying something 2 times in chat is not spam nor will it do anything. Though, if you do 3+ times, the filter will warn you to stop. People do avoid it though, but it is a slightly different message. About /me. I personally do not like the command but I have to deal with it. When people abuse it, that is when I have to step in to solve the problem with warnings, ect. It may not seem like a big deal to most, but when it comes to enchanting, it can be very irritating. Support, I would love to have it back so I can type two commands again.
Support, spammers just add one more dot to their message and bypass it and that hasn't stopped the advertisement from other servers. I bypass it too by pressing / and enter after each command (/home (enter), / (enter), /home (enter) )and if this is filtered too I'll just type /(any key) (enter). Have you tried enchanting many items or turning a double chest of cactus to sand (skyblock) this way? It is just a waste of time and lately they have been too many of them on the server.
