Exif data and file names for stock

Hello 🙂 

I would like to ask what should I do with exif data before uploading a file to Adobe Stock? Remove it, leave it, reduce? Are there any recommendations?

Second question, is Adobe Stock renaming the files after upload? I mean, if someone buys an image can he/she sees original name of the file or something like" IDxxxxx.jpg?

Thanks in advance!
