Best broker for scalpers?

I've heard that AccentFfrex started demo contest Master Scalper again.
They promoting automated trading offers a new demo contest for scalpers and traders use automated trading strategies. Did anybody use it? What would you say as to this contest?

Terms of trading for “Master Scalper” contest accounts:
1. Initial deposit of $ 1000;
2. Leverage 1:100;
3. For trading available 0.1 lot orders only

They allow scalpers in as much as each trade span nothing less than 7minutes. I see this as a rule with many brokers too.
