Paraphrasing doesn't help either.

I don’t quite know where the forum stands on accidental plagiarism.

Plagiarism destroys your reputation, the penalty is an immediate ban of the user. IMHO many newbies tend to plagiarise because they don't read the rules and guidelines.

Many writers get ideas from other writers, but you cannot copy a chunk of sentences from another writer without being accused of plagiarism. Paraphrasing doesn't help either. Copy and paste isn't wrong but claiming work as your own is.

I had the curiosity at some point last year as to how far back in people’s history did the rules apply (see A couple of quick questions related to forum rules). The answer was that there is no delimited timeframe for rules to apply.

If I recall correctly, my curiosity was aroused when I checked the forum rules to see when rule 33 had been written:

- It was present at round November 2016 (rule number 33): https://web.archive.org/web/20161121133329/https://bt.irlbtc.com/view/703657.0
- But not in May 2016: https://web.archive.org/web/20160506061123/https://bt.irlbtc.com/view/703657.0

Of course, these rules are basically a privately applied based guideline, and obviously can apply to whatever timeframe the Forum wishes, with disregard to the fact that the rule infringement may have been committed prior to the rule being stated.

The fact that the rule on plagiarism (for example) seems not to have been introduced until somewhere between May and November 2016 could be controversial with regards people being banned for plagiarism committed before that period. On the other hand, we could understand that all rules are fully retroactive and that’s it. I personally would prefer a 3 year timeframe or so, but that’s all it is, a personal preference.

Plagiarism can be accidental or intentional. Example of intentional plagiarism is when a post is written in one language is rewritten in another and posted in local board without citing the original poster.

"A hardware wallet is the best option for holding your cryptocurrencies long-term".

Obviously this shouldn't be bannable simply because it's very common information.

It would be easier if newbies read the rules before posting but they don't obviously. Its like buying a device and not reading the manual. Mistakes are bound to happen. Same users do not read the terms and conditions before signing up
Thanks! Maybe B&H would be more suitable for this kind of discussion. And yes you're wrong the purpose of this post wasn't to complete post quota.
Then how do you explain the cases of users getting banned. If you strongly believe the thread is useless you could simply just ignore. No need to bump it further

Perhaps though, there is wiggle room to make it manifestly clear, by including a clear reminder when creating a new post (something along the line of what is mentioned in rule 33 + the example, and emphasizing on referencing the source). This has been commented before on multiple occasions, is seemingly easy to do, and shows some good will to trim the number of cases we recurrently see. Nobody would be able to claim ignorance from there on, which is what we often read.
