This morning, several friends complained about the inability to transfer links via Skype and asked to check the computer for viruses. Having asked in more detail, it turned out that skype cuts out links from the popular online store dx.com (perhaps the other ones that I use only affected DX).
Update: Links to group chats are uncensored.
Update2: MERRON clarified that when sending from old clients, messages arrive uncensored. Tested on skype 5.5 for Windows XP / 7. Perhaps it is the client who sends the messages somewhere for moderation.
Update3: A topic has been created in the Skype community forum about this , all new topics are redirected there.
Update4: At noon on MSK, the following message appeared in the discussion.
On my win | linux | android clients, links with dx began to reach normally. Nevertheless, the fact of having a censorship instrument remains a fact.
Update6: the filter also proved www.kinopoisk.ru and www.wildberries.ru
