Nextcloud Account Giveaway Issues

Hello Friends, I have this small website and I am going to host a giveaway from my website. I am planning to giveaway 10 accounts from Nextcloud after installing it on the server. Can I do this? I mean is it against the TOS by any means? Or Could I land into any trouble for the same? Please let me know so I can proceed with the same.
