I removed that rule (before the start of the competition) because there was too much danger of name collision and it's a bit of a mouthful to say the prefix ahead of all the entries. The current rules have not, and will not be changed since the official start date- to be fair.
Nothing has changed since the start date.
But yes, there was a little bit of revising of the terms (loosening only) before the start date was reached. It's my first time running something like this, so sorry if I haven't been 100% on the ball.
The important thing is that I haven't changed anything since the start date was triggered.
