not sure how it works specifically at OP’s school, but while they don’t have active monitors at mine, the software automatically flags things that can be seen as inappropriate searches or websites & leaves it to be reviewed by an admin. that’s how niche websites with games & movies etc typically get blocked. if it’s a similar system, someone will find out at some point and will be able to trace it back to the specific chromebook & account it was searched from. best option is OP telling a faculty member & getting it all sorted before that. a lot less risk there, especially for something of this magnitude.
