I didn't know about this. I have looked into it, and found that there is a small group of developers who follow each other's private secondary Twitter accounts. Inside this closed group they share jokes and vent frustration with sarcasm and hyperbole.
Some long-time employees and team leads were part of this, but it's a small group. (T & J are our senior managers in this area, and not part of this -- I want to make sure you know they weren't involved. They don't even drink, so being 'drinking buddies' has no impact on advancement -- we promote on merit.) The ones who were involved that I've spoken with feel terrible that you saw their tweets and misunderstood their intent.
(The fact that you've had this experience is also a useful reminder to them that, ultimately, everything you put in a computer will be public.)
It seems silly to address things point by point, but you're painting a terrible picture -- and one that may be a bit exaggerated, or at least lacking context. I'm told that the single photo of a woman, for example, was a screen capture of a funny/cautionary automatic-data processing failure at another site where something inappropriate was tagged and presented as the result of an innocuous search term.
The other posts reflect sarcasm and flippant comments in response to the petty issues of daily work, technically-uninformed requests from users or co-workers, etc. Silly venting in what they thought was a closed group of friends who wouldn't be offended. (If you've worked in development for five years, I'm guessing you've learned that sarcasm is a popular mode for developers, even though it's not a fruit of the Spirit.)
Poor judgment? Yes. Disappointing? Yes.
Reading your comments it feels like you're feeling a lot of frustration, and trapped by your circumstances. I'm sorry to hear that. If you have been here more than five years, you were here when development was much smaller, and I was working with every developer daily. I'm really sorry that, even with that long history, you don't feel comfortable bringing this to me directly. I hope you'll reconsider.
Nobody should feel trapped in a job. I'd be happy to work with you in a safe environment to talk about a better fitting position for you here, or how to get out from under your mortgage situation.
Again, I'm very sorry you aren't having a great experience here, and hope you'll let me help you directly.
