You were most likely trying datacenter proxies. No surprised they didn't work, because as the name suggests, they come from datacenters, similarly to VPNs. This is why they easily get spotted and entire subnets get banned (along with them your accounts go down too).
What you need here is either a residential proxy, which comes from a real internet service provider (therefore very hard to distinguish) or a mobile (4g) proxy. This one is best suited for social media, but also the most expensive. However, if you have the budget, go for a mobile proxy and if you want to save some money, then resi proxy is your choice.
