Sequential IPs for Tweetattacks?

Hi, I have 50 private proxies for use with Tweetattacks..they are in 3 different subnets, but the IPs in each set of subnets is in sequential order. I see that Squid Proxies sends you non-sequential proxies. How likely is Twitter to ban a whole subnet(or at least put 2 and 2 together and starting banning accounts more quickly) if there are like 20 sequential IP addresses hitting their servers hard throughout the course of the day? I'm not doing wait and reply stuff, just following/unfollowing and tweeting without links. Thanks

I guess what I am really asking is should I just get proxies with non-sequential Ip addys or just use the private proxies I already have?

non-sequential is your choice

go for non-sequential for sure! If they are sequential the whole IP block will be banned pretty easily
