Zepla's video was simply showing the telegraph thingy from a different reddit post that you could clearly see from 2s of actually watching and comparing the reddit thread titles, Bagel wasn't using it. She even says right after the Bagel clip: "Here's another thing I want to show you." Which shows the two clips were unrelated. If you're going to argue he was banned for certain things, its best to get properly researched on what caused his ban.
The only thing he got banned for was the numbers under buffs add-on. My group watched Bagel all the time while we were world racing for information gathering, there wasn't any time at all before his ban, that he was using telegraph hacks. That being said, think about how ludicrous your statement would sound. It took nearly half of the first day for most streamer groups to even see the mechanic that telegraph hack is showing in that clip - without knowing how the mechanic functions, its impossible to make a telegraph hack since you have zero idea what you're supposed to be telegraphing. These hacks would have come, a week later after DSR was released at the earliest, a far cry from day/week 1.
I know of 5 different friends who used those plugins for ACT that avoided the auto-logout during EW's release and they worked flawlessly as they were still online in the same spot 13 hours later. Square has never 'trapped' any game coding; its a waste of dev time, money, and resources to do so. The most they do on a new patch is scramble the opcodes most add-ons use to communicate with certain variables in the game.
Also nice dodging; the burden of proof in this instance falls on you if you want to make a statement on official wording without sourcing. That being said, the post you're referring to is them talking about methods of circumventing the afk timer they patched out of the game; not 'trapping' the game code, which has a massive different connotation since it implies an undercover change intent on exposing something, when all they did was announce they were fixing several exploits players could use to get around the afk timer, the literal opposite of a trap which requires ignorance on the target's part to fall into it.
