I find Ankita’s decision valid. When she was given a chance, I read that BB said that according to the rules what would be her decision. She said to evict him. But after Salman came and explained she changed her decision. If she felt that he can get a second chance, there was nothing wrong in it. At that time the fight happened I think she didn’t expect that Abhishek would slap Chintu as poking happens most of the times in the house. She and others told Chintu to stop, he told that to Salman. So she did tell him to stop. And after that also she saw Isha poking Abhishek in the Ghulam task then maybe somewhere she felt that Isha and Samarth were poking him a lot. After that Salman telling them about the excessive poking so she changed her decision. She guessed it right that BB wanted him back and she felt to give him a second chance.
