If you are sharing a forum's link at public place, you may shrink the post url.
For example, https://forum.sketchub.in/d/8-sharing-forums-link could be shrink to https://forum.sketchub.in/d/8 .
Facebook's moderation bot have blocked https://sketchub.in domain, hence forum links are not shareable at Facebook, Instagram & Messenger.
