I am writing something that may help you mitigate this embarrassing and tedious problem!
In my case I do not have a good network speed or a powerful computer (I have a maximum of 80Mbps of network speed and I have a quad-core PC -I3- with 8Gb of RAM), however with is strategy I have had a better performance and use of RuCaptchaBot.
I tell them what I do:
Open the Chrome and clean the web history (do the same if you use other browsers -Mozilla, Safari, Opera, etc).
Reboot your router. This step is fundamental.
Close Chrome, do not use it again while working with your bot. If you need to work with a website and / or have your emails open, especially an email similar to the one you use to connect to RuCaptcha, use Opera, Mozilla or Maxthon (this last browser has been evolving quite well in recent years); recommended to use browsers in incognito mode (Ctrl + Shift + N in Chrome and Opera, Ctrl + Shift + P in Mozilla, File> New private tab in Maxthom) and thus prevent the accumulation of cookies and other information in the browser history.
Start the 2CaptchaBot or RucaptchaBot in "Run as administrator" mode.
Once the bot is open, go to the Settings button, delete the cookies (Delete Cookies) and then press the "Incl. Proxy "select the option Never and start using (press Star) without opening your Gmail inside the bot.
Thanks to these 5 steps your IP will not be banned, and therefore it will improve your performance while you work with any of these bots. Additionally I give you the recommendation to do a sixth step to optimize the work: clean cookies every 30 Captchas resolved, which will help you to reduce waiting for new Captchas and thus be able to process them in the shortest possible time.
Observation: the amount and time of Captchas will depend on the network speed of your work area, the capacity of your Workstation (PC, laptop, Smartphone, etc.) and the reputation that you are achieving. For example, when you exceed the barrel of the 2,500 Captchas completed you will see that the number of infinite Captchas is decreasing. That is, when you reach 5,000 Captchas, this problem is reduced significantly and the rate of Captchas completed per minute will increase significantly to the same as your profits!
If this strategy has worked for you, please, support me with your vote and and if it does not work out they let me know; I will continue investigating!
I hope this works for you, if you have doubts, do not hesitate to write me.
Happy Captching!
