It's been suggested by two people that it isn't useful for me to contribute English sentences with the same meaning.

[#8585999] I don't think I offended anybody. (CK) *audio*
[#8513112] I don't think that I offended anybody. (CK)

One of these people even accused me of doing this to "inflate my sentence count."

I wonder if you, too, think this isn't useful and that I should stop doing this.

I am not offended by that at all and I think that it is entirely ok and even useful.

It is always good for learners to know all the variants of the same sentence, if possible: with or without conjuction, using different word orders/ patterns, etc.

I do the same at translating, albeit I don't add all the possibilities every time.
