You'll still have to make sure that you clearly post that it isn't your artwork and that you have that artist's permission to post said art. Given your past infractions I can guarantee that people will be checking.

Once again the details are in the AUP:
The By You/For You Policy
1) By You:
You may post any Submission provided that the submission is an original work created by you. Joint works and collaborations must give proper credit to all contributing sources.
2) For You:
Fur Affinity allows users to post Submissions created for them provided they have the original artist's permission to repost said work. Credit must be attributed to the original artist with citation that the work was not created by the submitter.
