Bug - Site seems to be converting my imgur links

In this post
https://vbulletin.org/forum/showpost.php?p=2603459&postcount=546

I am posting EMBEDDED images via Imgur. ( BBCode (message boards & forums) )

After a bit the forum is changing them all to
https://vborg.vbsupport.ru/

This is new and bizarre.

I just looked back at all my posts over the past years all of them now the imgur images have become https://vborg.vbsupport.ru/
