This may seem like a stupid question, I have zero experience of these things, but I thought the whole point was to make “arrangements”?
That’s like aw banning you for booking an escort Shirley?
Seeking is trying to get rid of their "sugar daddy" reputation that made them famous. Now they seem to have shifted to be a "Luxurious dating site".
Everyone knows how things works under the hood, and that's why many members insist on moving conversation as soon as possible to WhatsApp or other communication means.
From Seeking T&C:
The Website may be used only for lawful purposes by individuals seeking relationships.
And they can ban you for this.
Using the Website as an escort, prostitute, or for compensated companionship, or using the Service to promote, solicit, or engage clients for an escort or prostitution service, compensated companionship
And finally, they make it very clear what is the website about:
This Website is only a venue—it acts as a venue for individuals to post personal and contact information for purposes of dating
I highly doubt that it's going to work in their favour. Their brand is tainted with the sugar daddy stuff.
Although, you will find in this thread people commenting how delusional some girls are, as they think that they can get money by just being pretty, and sometimes not even meeting.
