get taken in (by someone or something)
1. To be fooled, swindled, cheated, or beguiled (by someone or something). It galls me how many people get taken in by companies' claims that "the customer matters most." You spent $1,000 on some cure-all pill you bought off the Internet? How could you get taken in like that?
2. To be adopted, looked after, or given foster care (by someone or something), often in an unofficial or informal manner. At this shelter alone, nearly 200 abused animals get taken in each year. My younger brother and I got taken in by our aunt and uncle after our parents were arrested.
