My sister-in-law regularly sends me stuff which has her worried… and I use several sites to checkout the facts… if I can… hopefully to calm her fears or … on the other hand… to confirm her fears 
One of my favourite sites is
in fact there are lots of sites and everyone will have his/her favourite…
so, which is your preferred site ??? the more the merrier… 
On this subject, I just came across this one 
I find the gov’t site about scams has useful info
https://www.economie.gouv.fr/dgccrf/infos-arnaques
And there’s also a page to register scams
https://www.internet-signalement.gouv.fr/PortailWeb/planets/Accueil!input.action
And for current concerns I like the WHO site
https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/myth-busters
Hoaxbuster and slate.fr are not bad
Email from EDF:
Some malicious people are taking advantage of the current situation to try scams by email, by phone, or even at your home. Their purpose is often to recover your personal data, a RIB or a credit card number, to extract money from you.
Have you received a questionable email? Do you want to make sure that EDF is writing to you?
Find all the useful information on our “Scams and Phishing” page:

These words from EDF are echoed across many main supplier/bank websites… and with good reason… they are warning us against giving out details… warning us to be sensible.
So, please folks… think twice…then think again… and then say NO !!! keep your personal data etc safe from the scoundrels who are trying to rob you…
