IP address question

I need to create a few accounts on forums for posting aft links. not this forum of course lol. I know that if I go out and create an account in a coffee shop using the wifi it'll be on a different IP address at home.

My question is if I were to access that account from home, would the forum owners see that i'm using it from the same IP?

So to make it clearer:

Home account created with home IP
Coffee shop account created with coffee shop IP

But then both home and coffee shop accounts are posting using home IP.

Will I get caught?

Thanks for your help

How about proxies different browsers and not using your browser in full screen mode?

I don't know where you live... but usually for the price of 2 coffees, it will cover the months cost of vpn or proxies.
So you can use proxies or a vpn. There is a section on this board offering proxies for sale

Yes you will get caught you cant use same ip with 2 accounts or they will be connected.

I don't think that will be a problem, Imagine your friend creates another account from coffee shop.
Now you and your friend both can login from the home IP.
I don't think that will be a problem unless you try to spam the forum or do some naughty stuffs like replying to your own posts, etc.,

multi accounts from same ip is reason of ban in most of forum.

you can use proxies, it will be much easier to use different accounts with different proxies.
