I have read about plagiarism in the forum which is a great offense here and anyone who is caught will get banned from the from. If someone wants to copy and paste here,he must provide a link to that which he has copied from.
I am not an expert here but I will honestly answer to your queries on my experience on this platform.
Yes, if you do plagiarize, you will be banned permanently, and if you want to copy and paste something, like some's statements then i prefer you to use the following syntax and put the statements and anything (text) that you want to paste.
[quote]Your text here[/quote]
and do not forget to put the source link. Because if you are copying something then you have to declare that you are quoting it and have to provide a source link too.
You can check the following posts where OPs have copied and pasted whole articles from the website and didn't get struck for plagiarism.
i have personally used this method sometimes and didn't get penalized for plagiarism so i think that's safe.
I don't know if someone wants to use a picture on the internet without providing a link to that picture if that user will be banned for his action or I must also provide the link to that picture which I used. Is using someone else picture without providing the link also plagiarism
TBH, i have seen many people who have shared pictures from the internet and didn't share the source link with it, but i have observed that most of the members do share the source link to the image, and its the best practice so i think putting a link to the image will not cost you a lot so why not putting it. And it will also help readers to redirect to its source for confirmation, and it will save time too.
Using AI generated post, which I know that is not encouraged in this forum, what will be the penalty for such action,is this the same as plagiarism ?
AI, is highly banned on this platform there had started many topics and threads on this topic (AI) and many accounts have been banned from the origin of ChatGPT. If you copy from AI content generators and pasted it here it will be considered as plagiarism and you will be banned without any warnings. So, stay away from it, but i think at least you could use it for other purposes like to learn something not to just copy and paste text from there to here to earn trust and respect.
