All good on my side (https://perchance.org/clean-text2image). I think that user is generating some violating content (e.g. child porn etc) hitting the gallery auto-delete filter. Normal NSFW are working fine (too fine on my gen =.=").
Definitely not technical error.
Thanks for making a wonderful facility for us. FYI, T2I is really awesome on Perchance. Keep up the great work!
