Assalamu ‘alaykum Shaykh, Is it permissible to use a tool that collects publicly visible online reviews, even if the websites’ terms of service prohibit automated collection? JazakAllahu khayran.

The details here are lacking, but if this is something that is prohibited by a certain company, and despite that, you go and still collect what they don't want you to collect, then this is not allowed because you are violating their conditions.
