Fanfic Recs page linking to offsite lists

Was looking at FanficRecs.Alex Rider in the course of planning a split-off for the live-action series, and noted that the page includes this:

• Several longer fanfic rec lists can be found on Tumblr, here, here, and here

As far as I'm aware, this is against wiki policy, as all recommendations need to be signed? I'm aware this is a rather minor issue, but can't seem to find a relevant thread for it.

That is true. Additionally, Weblinks Are Not Examples.

Granted these technically aren't examples since they're in the page introduction, but I think it still counts from the spirit of the rules.

Thanks for the confirmation, I've deleted the links.
