what is happening with my twitter account?

Hello all,

Please help me since I am not proficient on twitter ,

So someone sent me a direct message with a link to get a lot of followers , a link that looks like this twitterfollowers.mobi , so I kind of clicked on it and signed up with twitter, but the thing is I keep getting a lot of messages with bunch of websites that want you to subscribe and get followers. Now please tell me how to get rid of it, I really don't want that many followers , and this is not the issue alone, but I am following some professional people, like professors, coworkers and they keep on getting those messages with links from my twitter account, and I keep deleting the messages but I get a lot more from people I don't know!

Please help me or guide me how to get rid of those links whether received or sent messages !

Thank you , and I am sorry I typed my question very quickly via my phone.

Regards
