In fact, I don't know how to type Chinese. Therefore, I use English to communicate in the online world. However, I am really weak in the use of English and I always make a lot of spelling and grammar mistakes. As a result , I was scolded by someones, and even they ask me to use Chinlish instead of British English.
Here are some example of the mistakes that I usually make.

Do you think that it is important to use Formal English in the online world? sosad
p.s. there are still lots of the mistakes in this post.

From the passage above, I didn't find any grammatical mistake.

Under normal circumstances, I would like to use Formal English to express my ideas or views in the Internet world, rather than using Chinglish or other informal words.

It does not only help me to improve my English typing skills, but also train your gramatical use.

Therefore, I support we use Formal English to type passages besides using Chinese.

Thanks a lot.

however, it is hard to avoid any mistakes If I 'd typed faster ,I would had made different mistakes . As a result ,some people in another forum would scold me.

Well...I don't think we should always use Formal Eng. while surfing any forum sites.
Rmb, Formal Eng. is often used in official letters or documents.
Even native Eng. speakers use abbreviations or so called informal Eng. to communicate in daily life.
However, I suppose you're talking about the problem of using Eng. with loads of mistakes.
Actually, you should not be bothered by what other ppl might think.
After I've looked through your posts, I think you must have tried your best to avoid any mistakes.
Indeed, even some native speakers would make mistakes!
Besides, I bet not everyone has such good Eng. skills as you, so what's the point to be bothered?
In fact, you can learn from the mistakes you've made and thus improve your Eng. skills.
However, I would also suggest you to learn Chin. Word Processing, as it is an adv. in your future (or present? ) career.

P.S. As a little reminder, the conditional you've used in "If I 'd typed faster ,I would had made different mistakes" is not appropriate.
It should be "If I type faster, I will make different mistakes."
In fact, if you wanna improve your Eng., you can try doing more ex.

I suppose using formal English in online world rather than informal one.
Since we are not native speaker of English, our level of English is very easy to be affected by the use of the language of us.
If we continuously use informal English, we may eventually forget the appropriate grammar and spelling of the language,
which may bring us very serious consequences.
However, using formal English in online world helps us acquire a better communicating skill outside classroom.
For the problem of spelling mistakes, I think you should take great care of your typing.
Such as looking at the word you type on the monitor to avoid any unnecessary mistakes.
