i love mag1k -- Not getting response from register page.

I am trying to register on the link, i click on the register link, fill details and click submit but i dont get anything. Also when i send the data via burpsuite through repeater i see a 403 error which says blocked by bitdefender.

Am i going the right path or am i supposed to do sql injection or javascript injection or bruteforcing etc. ?

I dont understand why someone who did this challenge a year ago only got 5 points and now its worth 50 points. Was this machine modified?

No. The formula for challenge points calculation is as follows:

challengePoints / 10

You can check all the formulas here, e.g. ownership percentage.

Would like a little help here, can understand how to register to that page.
