My twitter account keeps sending my followers messages automatically?

[Gabriel]

Sometimes, when I look at my messages, some people reply to me and one even said "go f urself". I then realize that a msg by me was sent w/c is always like this "Twitter might charge now? read this article". I didn't even send that to them, my acc send them automatically w/o me knowing. Its so annoying, i think my followers unfollow me because of it, they think I am really anoying with those useless dms sent to them. I didn't even do anything for that to send. I don't want to be hated just because i send those dms to them. If any of u know how to prevent this from happening, pls tell me. Thanks.
This is my account https://twitter.com/mal1kh0ran if you're sent these messages by this account, then again it's not me.
