will accounts got locked if i log in my accounts from new IPs everyday?
Common sense... think of a public library with 200 computers all on the same IP.
Do you think only 1 or 2 of these are using Twitter at any one time?
The only reason why you should use more than 1 IP is because Twitter have limits, both per account and per IP based.
If you try to [GET] too much from Twitter on the same IP within an hour, you'll be blocked from doing any more for a short period.
Therefore it makes sense to limit the amounts you use per IP if you're [GET]ing / retrieving something from Twitter.
You'll know yourself how many to use because Twitter won't be doing what you want it to do on that account, until 10-20 mins have elapsed and you're allowance is reset.
With respect that doesn't make any sense.
If you know what you're doing you won't need any more than 3-4 accounts?
Get real. I have one account with over 45,000 followers, another with over 25,000, another with over 20,000, another with over 12,000... the number of accounts is directly related to how big you are marketing and into how many different markets.
I have close to 50... in 50 different subjects and I'm confident to say I know what I'm doing.
4-5 is small fish. It means you're only marketing in 4-5 markets.
With regards to IPs.. I've been running over 45 on 1 (ONE) IP for almost a year - not had any problems at all.
It's not about your ip address is about your email address. you can open as many as you want on that ip address if you have a new email for each.
as long as u can create a new mails no need to go proxy
