Here is some excellent advice, from Matt Burgess, over on Wired UK, about Instagram scams:
How to Avoid the Worst Instagram Scams | WIRED UK
One of the best bits of advice to remember is that threat actors and scammers quickly congregate to any big story or human tragedy, such a the Ukraine Russia conflict, COVID-19, cryptocurrencies, fleeing refugees, ransomware infections – they have no scruples, anything to make money.
So when you see a flurry of posts wanting donations or offering help for your problem, especially if the story is in the news, treat them with scepticism until you can verify their authenticity. Better still if you are motivated to help in these situations or need advice to deal with issues yourself, don’t follow links on Instagram. Seek out the official websites of organisation who deal with these situations and donate there or follow their links to the help you need.
