Yep, it does.
When I joined, I had little experience on the internet, besides playing Blockland and Roblox. I wasn't used to criticism, so having something disliked was generally hard for me. As I spent more time on here, I began to mature and learn that I liked this place. I still was an edgy 9 year old friend, but I changed a bit. Later on, I made a Self Delete post because I was upset with the forum. Later on, I discovered one of my old keys that I thought I had lost. I played with that one for a while and then used it on my second forum account. That account was kind of a game changer for me, because I learned to survive and deal with negativity. Later, I made another account and used a key on it. I'm pretty sure all of you know that account, not going to mention it. I don't know why I made it, just wanted to look cool with a second on my hand probably. I switched accounts often, although I used HedRokkA more. Then, I was banned for 2 weeks on HedRokkA for spam. I don't remember the other part of the story, all I know is that a drama was made of Keith. I then got tired of people being asses to me, and I made a stupid threat which I did not take into consideration. I got perma'd for that, so I was off for a month or two. Then, I made my 4th account, Berint. I made a topic that I'm not going to discuss. I thought I was gonna get a ban for it, so I cowered down and tried to make better posts, hoping that a ban did not happen. Luckily, I did not get banned, maybe because Badspot thought I was new and didn't know how the forum went. Sometime later, I made the famous topic "Stupid special needs kids" or whatever the hell it was called. I got an enormous amount of replies, most of them were hostile towards me. Then I got some agreement and other stuff. I was fine, until Johnny Blockhead made a drama topic on me. I still am sorta neutral towards him for that, I would consider him a friend, but not my closest one. Later, I made some posts that got me banned. I'm not going to say what they were, but if you want, you can look through Berint.
I also have a lot of other alts. Not going to list them, just search if you want
So, in conclusion, yes, it does. I went from being a shy and edgy child to being a more hostile, energetic and mature person.
I can't say that I'm too different from my past, but it is applicable to say I have changed a bit.
