If you've seen otherwise, by all means share.
To quote PentaPixel:
Flickr Limits Free Plan to 1,000 Photos, Upgrades Pro Members
"If you’re a Flickr free member who already has over 1,000 photos in your account, you have until January 8th, 2019, to download photos over the 1,000 limit.
After that date, you will no longer be able to upload new photos to Flickr. And after February 5th, 2019, Flickr will begin deleting files that are over your 1,000 photo/video limit, starting from oldest to newest, until your account contains only 1,000 files."
No mention of if over the limit concerning uploads. So maybe PentaPixel quote them wrongly or Flickr changed the text (as they did before with the change of ownership notices).
ImageShack does not allow uploads on their free accounts so it would be reasonable that Flickr might follow their model.
