What proxy services do you use to increase limits and privacy?

I'm looking for a good proxy service that can provide a solid number of residential IPs and also help me hide a lot of sensitive data for various requests. I read about https://proxybros.com/reviews/packetstream-io/ but would like more options

Hey guys! Could you please tell me what are proxies? I have heard about it many times but I have no clue what it is. Thanks!

Proxies, in the context of computer networks and the internet, refer to intermediaries that act as a bridge between clients and servers. They serve as intermediaries by accepting requests from clients and forwarding them to the appropriate servers. Proxies can be used for various purposes, including improving security, enhancing performance, and providing anonymity.
If you want to know where to buy them, I recommend paying attention to these mobile proxies. I have been using them for quite a long time and in all this time I have not had any problems with these proxies.
