Write it in a txt document, then copypaste it.
That is an input element, supposedly the default length is 524288 characters, but I advise to keep it as short as possible.
Maybe you can post here your problem and we'll see what can we do about it.
Also if you need to give a longer explanation, you could post it on the board what you use, so the users could discuss if your point is valid, if the thread should be removed or not.
On global level, only global rules matter, what you can find on the home page of Endchan.

the nature of the issue requires an impartial evaluation, I don't think it would meet that requirement if it were to be discussed among the user base. thanks for the info

You could hop on IRC and write. Then wait patiently until we notice and reply.

I reported the thread on IRC, I hope someone can take care of it soon

I'm sorry, I doubt anyone was present at that time from the staff.
If this is about doxing related, I can advise not to share any information with unknown people, what's given away it cannot be erased from the internet anymore. If it's already out there, nothing can be done, one has to be resigned and move forward with life, being careful in the future whom one trusts, and what information to share. Trolls are doing it for the attention, they should be ignored, so they don't get their pleasure, they'll get bored and they'll move on too. Yes, they'll poke for a while, but eventually they'll give up. They also use the already gathered information to coerce out more information, one shouldn't replay, it's saying "No!" by ignoring them.
If you turned to us it is very likely the Board Owner (BO) is also the part of the problem. On Endchan, the users create and manage their own boards.
If we - global staff - get a report we check if the post reported violates global rules. If not we leave up the content. Further than this no matter of the morality and no matter if we disagree with the content, if it is protected speech, it is extremely unlikely we'll violate the freedom of expression of the users.
