Busy But Not Steemit?

I can upload images to Busy through IFPS but not to Steemit in November 2018. Like I said before, I'm having this problem again.

Dtube Problems.

I uploaded videos to Dtube, through IFPS, in 2017 and 2018, but those videos are gone now not only on my channel but also on others. I've heard Dtube doesn't keep videos up forever, especially if they're lacking enough payout (rewards). How much is enough? Maybe five dollars. Not sure.

Busy Images.

The photos I uploaded via Busy may someday disappear too like my Dtube videos did. I have enough mana (RC) but can't upload. But this problem may go away in a few days like before. There may be a picture posting limit that is separate from bandwidth, from Resource Credits (mana). I just have not seen anybody mention what those limits may be.
