Translation tip, if it is a SCP-XXXX you can find the english version on the SCP wiki: http://scp-wiki.wikidot.com/scp-2010
You are also supposed to cite this due to the site licence.
Yes, they do, sort of. That would be the anomaly classification system, an optional alternative to sekt.

So, with the object classification, when the author is put down as far2 that usually means that the SCP was moved from the editThis wiki to wikidot, 134 is really old and is from before object classes were worked out properly.
According to the crom lookup, this article has an unknown author...
So licencing note, this doesn't contain a link to what it is based on which is a requirement for the SCP licence. Just needs a line in the final panel like the previous translator put in.
@ActingRikka Due to the site licence (cc-sa-by) all you need to do is attribute your source. The real problem is that anything SCP based must be under the same licence, which means anyone can copy it as much as they want.
