Bots are never enough, you know. I have a cross-platform twitter bot that works almost everywhere (desktop, mobile, cloud, etc.), supports up to 1000 concurrent threads running at the same time (thread=greenlet), supports socks/http proxy, can be configured to use +TOR as a proxy pool, includes different useful modules out of the box, ping me to get it for free (it has no GUI yet, but I'm going to add desktop/web interface soon)
iMacro is the best out there if you're looking for an effective way to gain more followers on twitter. The best thing about it is because you don't have to spend any bucks.
Yeah but not if you wanna manage 1k+ Accounts.
I recommend twitter.recuweb.me a social media monitoring platform providing tools to automate and monitor actions on Twitter.
I have a twitter bot called Tweet Frenzy, my bot can Auto tweet (spinable tweets) follow users based on tags, unfollow, auto follow back, favorites based on tags, retweet based on tags, tweet @ based on tags (auto replay), scrape and follow a users followers, scrape and follow a users following, scrape tweets and save, follow from a list, Auto direct messaging. All of our bots have proxy support and use ini files to save and auto load settings. Advanced time delays to make the bot go as fast or as slow as you want (and random delays). Stop the bot at options to keep your account safe.
