Hello group owners

In the last weeks I completely rewrote @AntiArabicScriptBot and @AntiCommandBot.
The bots traffic grew significantly over the last few months which made some inefficiencies obvious.
Rewriting was the best way to fix these mistakes and also simplify a lot of the code.

I've planed to rewrite the other bots @AntiHyperlinkBot and @AntiServiceMessageBot as well but before that I would like to collect some feedback about the speed of the new bots.

If you have some spare minutes, please start the old bots (@AntiHyperlinkBot or @AntiServiceMessageBot) and the new (@AntiArabicScriptBot or @AntiCommandBot) and compare their reaction time.
Simply send /start a few times to see which bots feel faster - no need to measure time.

Thanks for comparing and using my bots.

@AntiCommandBot Is currently not deleting messages in time. Telegram has been informed but they did not reply since over 2h. There is nothing we can do at the moment.

Please do not remove & re-add the bot it does not help at all. You may want to remove commands manually or you can just wait. The bot will clean them up as soon as it works again.

We do have the exact same problem with @AntiArabicScriptBot now :/
It seem to catch up but it may take hours to fully recover.
As mentioned before please do not remove and re-add the bot.

And it hit @AntiServiceMessageBot as well now. Still no reply from telegram.
As mentioned before please do not remove and re-add the bot.

I got several request to create a bot that removes "Russian". Cyrillic is of course used by many other languages than Russian.
Anyway I made @AntiCyrillicScriptBot which is completely BETA for now.
You can report bugs to @TheWordAlive. Also if you want to create an image for that bot you can send it to me.

Good news and bad news

Lets start with the good news first.
The latest version of @AntiServiceMessageBot
deleted over 100 000 000 service messages!

The bad news.
@AntiServiceMessageBot currently has serious problems getting updates in time as well as sending out message delete requests.
Sadly there is nothing I can do about this. It seems to be a problem on Telegram's side. But don't worry the bot will eventually catch up and it will clean up old service messages. As always you don't have to do anything to make it work again.

A serious connection problem has been resolved. All bots should work normal again soon. Some bots still have a huge delay because they are processing old messages first.
Please do not remove and re-add the bots it does not help at all.

As you might noticed @AntiArabicScriptBot and @AntiCyrillicScriptBot got a new avatar a while ago.
Today I officially release another similar bot.
@AntiHanScriptBot removes messages which contains han script.

@AntiServiceMessageBot has reached Telegrams limit for delete requests. Support has been informed but I got no reply by now. I'll update here as soon as I know more.
The bot will eventually catch up and clean all old service messages but it could takes hours with the current limiting in place.

After a "short" back and forth talking with Telegrams Bot "Support", that took months because their average response time is like 2 weeks, they finally told me that they wont do anything at all to solve the problem.
First they told me that the devs adjusted the limits for my bot, which did absolutely nothing then they just said they can't do anything.
The final "solution" they offered, is to just discard requests when limits are reached which would mean the bot simply does not work on the high traffic hours.

Here is the message from Bot Support:

I'm afraid that there is nothing we can do for that, you can keep handling them within the limits or just discard all of them calling getUpdates with a negative offset (remember that those updates will be removed completely)

In the coming days I will create clones for each bot that repeatedly hits the limits. I know this is not optimal but its the only way to keep providing valuable and reliable bots.
There is also a new bot coming very soon.

Finally the clone for @AntiServiceMessageBot is online. You can find it under the name @AntiServiceMessage_Bot.
