i think considering this as signed is a bit of an exaggerate use of the tag...

correct me if im wrong, but as a fault tag, its supposed to be used when the artists signature or watermark compromise the appreciation of the picture?

this... you can barely see this. its just a normal, pretty much harmless signature. in this case its not even affecting the composition or harmony or anything significantly.

i think this tag should be saved for more blatant cases in which the illustration as a whole is negatively compromised with the signature/watermark.

It is a bit odd to consider signatures a "fault tag" when there are images with far more obtrusive text (titles of doujinshi, magazine covers, etc.) that don't receive any tag at all.

The whole "signed" is misused (read: signed) but I just don't have time to correct
