How do I block an user from the site?

How do I block an user from Derpibooru? I want to do this just to prevent and avoid the person to harass on me or see my Derpibooru gallery or my profile

You can’t do any of that. If someone harasses you, report them.

@KittyKitkat
To re-iterate, if someone is harassing you, please report them.

I don’t see anything happening on your artwork, so assuming this is via PMs, click the “Report this conversation” link on top of the message and staff will be able to look into it.

Odds are, if someone is harassing you, they’re harassing other artists, too. And we’d rather not have those kinds of people on the site.

@Ciaran
The good news is when a user is banned, he can’t do anything, right? Perhaps enough time to think about what he has done before.

@LethalCandyman
A ban basically means that they can’t ‘write’ to the site in any way. That includes sending PMs or leaving comments or adding tags.

Ban lengths start at a half day or a 24 hour period, and then escalate depending on how many times someone’s had to be ‘timed out’ for the same problem.

The site’s been here long enough that people giving ‘lifetime bans’ 10 years ago have graduated from high school and might have careers by now, so we try to keep the ban length to something that doesn’t keep someone off of the site forever, unless they’ve been really obnoxious.

Eventually, Ponies will probably outlive us all, and at some point we all have to get along.

So, if someone is harassing others, we try talking to them about it, and if they are banned they can still come to support and talk with volunteers about what’s going on and maybe might be allowed back on the site.

Often, when people find out that they’re dealing with real people here, and not some sort of automated algorithm, they settle down and become good members of the community.

@Ciaran
Oh, I kinda get it, I guess. But yeah, with some hope eventually everyone will get along in the site. After all, our favorite horse show speaks about how the friendship is magic, right? Hahaha. Sometimes a harder order is needed.

@LethalCandyman
Even a show aimed at small children isn’t immune to criticism by older people, I’m afraid.
