To replace the one created by saxgod. Since Tumblr changed the API to use only oAuth, his stopped working. So far the bot is working good..a little too good. A few things I learned while testing the API is you cannot reblog and set your own source,link, or caption without first editing the post via the API. Tumblr only allows a max of 300 queued posts. I have about 300 queued with another 1100 drafts waiting to go. And you can only reblog about 250 posts per day. At the rate the bot is going it can gather easily 1000+ posts per day if I make it start at the beginning. I am not sure if there is a limit on the number of original posts you can publish in one day or there is a limit on the amount of drafts you are allowed. So far I haven't gotten banned. So my question is what would you find useful in a reblog bot besides the obvious. This bot is written in PHP and uses MySQL for reasons I will explain later and I have it set to run on cron. It can also run in sleep mode as the original bot written by saxgod did. I know many people don't have a server to run php but it was the easiest for me seeing as I have servers that run other sites. I did try writing one in autoit3 but it got too complicated. I may work on a better autoit version when I have the time. So here is what the bot does so far: -sleep mode or cron -set tags -choose specific post types -set status -limit posts to only retrieve a certain number at a time -set twitter status for posting to twitter -set caption -set click through link -set min and max note count -ignorelist and whitelist - auto like posts that are reblogged -like only and not reblog -email on failures -debug logging So what other features do you guys that use Tumblr would be useful in a bot. I found that it was easier to program the bot using PHP because there are many oAuth clients written in PHP and since you have to store the access_token and secret and figured I would use MySQL to store them and retrieved them when making oAuth API calls. I am very new to Tumblr and found it is a good source of traffic for blogs,etc if setup correctly. I also use iMacros alot with Tumblr for other tasks. Feel free to ask me any questions. I am a programmer by trade so if you have any questions about programming in general feel free to ask away.
