Guilded’s terms of use says “you will not … promote … work from home businesses”.
That is indeed weird out of context 
, but after reading the entire quote the purpose of this quote becomes more clear:
(vii) promote fraudulent schemes, multi-level marketing (MLM) schemes, get rich quick schemes, online gaming and gambling, cash gifting, work from home businesses, or any other dubious money-making ventures
From my point of view (not legal advice), this means fraudulent activities and businesses, which often take place at home, are prohibited as well as their promotion through Guilded.
