I have almost finished my twitter tool for converting aged accounts based on my niche and creating their applications including the mobile phone step. However, I couldn't figure out the following issue. I hope I will make it finish and put it here for public use after resolving the issue. My twitter-bot works as api-based and I need to get api keys for each of my accounts. I have created many accounts including the applications in past one year and there was no problem until this day. Now, twitter occasionally gives me an error while creating applications consecutively in a period. The error says: "We protect against potentially abusive behavior. Your request has been rejected for now. Please try again later or contact Platform Operations through...". After successfully creating an application for an account, I do the followings before continuing with the next one; - clear cookies - change my proxy (private ones) - change browser's user agent string However, I am still facing with the issue. After waiting a couple of 10-mins, I am able to create the new application. Based on my trials I can truly say that twitter gives the error for my PC. It bans my PC from creating new applications for some time. Considering the above changes I've tried, do you have any idea about what else twitter looks to my computer in order to identify it is me? I would really appreciate if you can help.
