I guess, it depends on the age/history of the account but you will be flagged for sure.
I would avoid to log in from an IP different from the country of origin.
You need to get a VPS/VPN to operate on your account. Lots of informations in the forum and members more expert than myself.
Btw, if you operate from Germany it is better to have the GE flag. This will help members to give you proper "directions" to help you.
Get yourself the stealth guide. Lots of useful informations there.
Very likely.
You MUST match the country's IP - at the very least.
Its is preferable that you also match the general area of the account's address.
There are several threads and many opinions with regards to what a good IP solution is. I myself am not overly fond of VPNs. Others prefer it.
Bottom line - do your research.
