“Just a moment” is probably the anti bot/anti DDOS service that particular website uses kicking in. A real website would interact with the web page and redirect before most people would notice, but bots and scrapers grab the lightweight HTML and run with it.
There is no good solution for this. If you’re the instance admin you could configure something like Flaresolverr to bypass bot protection pages, but you’d still need to update Lemmy to not grab the first page requested and wait for the redirect cycle to complete first.
As a user you can try picking links to sources that don’t have this type of bot protection built in, or you could link to the AMP page which is usually cached on Google’s servers without an anti bot system active.
Lemmy, and ActivityPub in general, is quite bad for privacy. To the point where I doubt it’d be legal for a company to host a server within the EU. Everything is handled by volunteers and amateurs. Privacy policies are bog standard or barely enforced. You have no idea what servers are using and selling your information, and any server can follow basically any community.
The easier it is for someone to create a new account after getting kicked or banned, the more likely it is that other servers will block that server and leave you with a near useless Lemmy account.
