Lol the site blocks it automatically in order to deny the free linkbacks, clicks and search engine ranking.
The thing I liked about them is that If anyone asked a controversial question, I could find all the controversial topics there with sources and read up on them and then go on the counter- websites that went through their accusations point by point, I could then research more for myself, they're not bothered about facts even when you email them with clarifications so I slowly grew out of giving them free clicks.
Their lies help new people studying Islam to see the attack on the faith and realise that there is a concerted effort, and since their lies insult the intelligence, intelligent people accept islam on a stronger and less shakeable foundation.
Since Islam is the truth, they will only reinforce the truth and throw a spotlight on it, you have nothing to worry about - but the liars need to worry about their blasphemy towards Allah.
