Just asking since I saw somebody who got banned for it in Ban list, but I've seen a bunch of people do it.

What is a dt?

If they don't tell the person they're dueling beforehand It could be considered a scam.

So basically yes you can get banned by doing this.

K thanks Snook.

What Snook said is pretty much correct. Just want to expand on it a bit here with the rules source.

If you check out the duel rules here, you can see that point number 3 says:

These are the rules/guidelines of duels and it's what we recommend you should follow or at least base your dueling practices on. That said, the duel is between the two parties dueling and if they both agree and are happy with what's going on then whatever, it's your business. As it says in the quote though, if something happens based on the non competitiveness of the duel that you were aware of but now don't like or agree with for whatever reason then we won't help you because it was your own fault. The key concepts here are awareness and acceptance. If you trick someone into a shitty dueling mode and they don't know or agree etc etc it's still against the rules.
