If that flies, it's a great tactic. You can't just use the data from site A, so you build anonymous sites B, C and D who use the data from site A, and use the data from those sites instead. "We didn't source from A".
It's not a great tactic if the owner of site A decides to sue you and subpoenas the hosting providers for B, C and D. You can only get away with it as long as you aren't successful enough to draw the attention of anyone with money to burn on legal fees.
