I can't provide proof, but I _know_ that I tweeted @adom_dev around the time of it's kickstarter and one of the Baldurs Gate EE devs about gemrb around the time they announced that project.

Both tweets are gone.

I don't think those tweets are gone.

The "Tweets & replies" section of your profile (https://twitter.com/eggsome/with_replies ) has two tweets that seem to match your description:

I can't prove that it was deleted. My first tweet appears to be from 2012 but I joined in April 2007 and definitely tweeted once then. (I was wrong about it being 2006)

I'm pretty sure that I changed my handle at some point. I'll try to remember what it was and search the internet archive.

How does one prove a negative? A deleted tweet from 2006 where nobody has taken a screen shot. It's not an active account like POTUS with the entire world watching specifically for catching deletes. I'm seriously asking

Internet Archive. Account metrics. Cached search results. There are probably a number of potential ways.

That doesn't seem like a big deal at all. They don't do blanket removals of tweets.
