I am quoting the image part for visibility. Staying true to my post here, I'll guide you to raise a flag if you deemed it necessary. The shortcut is to simply click this button, and you can choose which type of flag you deemed fits your situation better.

If you want a comprehensive steps, though:

1. Go to Betnomi's profile and click the button of "trust" on that page

2. From the "trust feedback" page, scroll way to the bottom of the page where you get to the point where you can leave feedback [you can leave a negative one for them too if you want to]. Right next to the negative feedback, there's a link to raise a flag.

3. From that point, to which you'll be redirected to the page below, you can choose which type of flag you want to raise.

Flag type-1 will only need 1 DT support to be active, but it's the lightest flag and only appear to newbie and guests. If I may judge from your situation, it's more fitting to raise a type-2 flag [a violation of casual or implied agreement], it'll require 3 DT supports to be active, but judging from current situation, I don't think you'll find any difficulties to get [a lot of] supports. You can arguably raise a type-3 flag too, considering that they violate a written agreement [their ToS], it'll also require 3 DT supports. The decision is yours.
