Account log-in suspended for suspicious activity, no clue why

[KraggyKor]

i get that sometimes, does setting a static IP on my end help to prevent this , or does it depend on my ISP ?

A static IP should prevent this but you need to get one from your ISP, you can't unilaterally set one and many ISPs don't provide them, or if they do they'll charge for them because they are usually associated with business customers.
