Doesn't matter the amount, some people have 10k. Its how fast you do it... don't go over 200 in a day, I would split them into intervals of 50 (so don't do the 200 ads all at once, spread them out)
I haven't seen any limit when friends are added and messages sent manually. Bot actions are limited and remember, log files never forget, so bot activity could get you deleted now or anytime in the future. I firmly believe that MySpace will eventually have a massive account deletion(based on bot activity) sometime in the future that will greatly increase the quality of the community and make it even more attractive to advertisers. That would be the prudent move businesswise.
So I guess your account gets banned, then what, you start again? But would myspace check your IP and ban it?
Make sure the titles of your messages are different (even if you have to double space, triple space) and also > spread these out as well.
I've had accounts get banned/deleted after sending too many friend requests. Since then i have dropped my bots to less than 50 friend requests per day and haven't had any problems.
what I'm trying to do, which thats a lot more time is add friends and sending messages at the same time....then if the reply to my message start a conv. with them....to make them believe your a real person.... Takes a lot of time but...you're getting real people as friends I'll keep this updated on how it goes for me.... *adding max of 200 friends a day
