isp/ip change

i live in brasil , what will happen to my accounts on the trackers if i log from a ip of another country?

probably nothing.

an advice: write about your problem in your profiles, so staff can see it

it depends. it shouldn't have any negative effect if you're being legit.

inform the staff first ... i kinda had a bad experience with a site ..

go to irc and talk to staff beforehand. usually ip changes are deemed as trading attempts. so as long as you are informing them in advance, it shouldnt be a problem. also as far as possible, dont change your email address and password. if all 3 - ip, email and password change in a short period, chances are the account will be banned.

for safety you can tell the staff
and explain every things to them

I agree with talking to the staff. Usually they'll put a note on your account, so you don't get banned.

i live in uk, i recently checked a couple of accounts (mainly to see if my comp was still on at home and not shut itself down) while on holiday in egypt.

nothing happened, don't suppose its any different from logging in at work instead of home etc

on strict sites(usually higher level), you should tell staff.
