TSR?

I don't know. Sorry to hear you're having this trouble.

Honestly, I still have a mod I made and uploaded over a few years ago that is still pending to be uploaded. I think TSR moderators just take their time when it comes to overseeing the uploads some due to copywrite or theft of another creator's creations. Also with all the malicious adds on there if you are not a member causes a lot of lag time too. This is from my own experience. I just ended up giving up and canceling my upload.

Can't speak specifically for TSR but I uploaded stuff to mod the sims in the past and it just took a while for them to review it. Sometimes they'll review things and you'll get a message with changes that need to be made so maybe check any notifications on TSR?

I think in general CC is mainly on Tumblr now, with people uploading it on simfileshare and then sharing it to Tumblr but it's really hard to reach anyone that way.

I've just received a reply from them with some generic msg telling it usually takes 5 working days to review the submission and than listing all possible reasons why it can take longer, including covid situation. Considering your experience, I'll leave it there for now to see if it's going to come through eventually, but I will not hold my breath lol...

What site than would one recommend for cc uploads?
