Docomo and signed emails

Some Email server run by Docomo and KDDI Japan seem to reject a ton of spam from a Brazilian botnet that uses us as a faked sender address…
This slowly started in April but has massively increased in volume this month.

Background


Emails claiming to be from us must be signed with a secret, cryptographic key that only we have. The corresponding public key can be found in our domain name entry. So every email server can check that an email it receives is actually from us. (This is called DKIM.)
In addition we also list the IP addresses of all email servers that are allowed to send email with us as a claimed sender. (This is called SPF.)

How do we know all this?

These are summary reports sent back to us from email servers that get our emails.
(This is a mechanism called DMARC.)
Red means it checked a signature and found it missing or invalid.

The reports do contain the IP-address and hostname of the email-server trying to send.
Most of them are dynamic IP addresses of DSL customers in Brazil
So it’s a fair bet that some botnet is trying to send spam with us as a faked sender.

Fuse blown

Looks like tonight 2:54 the fuse in the room where we have the NAS with all company data blew.
At 3:05 it reported 44min of runtime.
At 3:51 the battery was low and the NAS was shut down properly.
We came in early at 7:35 and are currently checking the situation…

Sidewinder restocked

We got a delivery of Sidewinder Creations toys.
All toys are back in stock.

(Yes, postings in the category „Disturbing Dildo Deliveries“ are basically copy&pasted.
There is just nothing original to write about such a thing but many people are waiting
for toys of a specific manufacturer to come in, so it’s important we post these.)

A delivery by Exotic Erotics just arrived

The delivery, that we told you was on it’s way, has arrived.

Stock status

All but 2 of the 142 Exotic Erotics models, are now in stock.

Custom toys

We do offer custom toys to be included in the next order.
Please contact us early and we’ll create a custom product for you to order as soon as the next shipment leaves the factory and we place our own restock order.

High bot traffic

We are experiencing unusually high traffic and the reason seems to be ChatGPT trying to scrape the YiffyToys shop with all it’s filtering functionalities for multiple days now.

This also causes the cache of rendered pages to regularly overflow it’s quote and be automatically flushed.

We are investigating options for rate-limiting bot traffic.

Update

Most of the traffic (over 40Gb in a day) was caused be ChatGPT training it’s „AI“.
In total 2/3 of all web traffic came from bots.
We have blocked all the „AI“ training crawlers we could find and some „SEO optimisation“ bots that serve no purpose other then to waste bandwidth.
We have also rate-limited search engine crawlers.

The legitimate crawlers now get 4 sitemaps that are generated every day.
They list the last modification date of all listed pages, so crawlers don’t need to revisit them.
They prevent bots from getting lost in dynamic navigation.
(e.g. the extensive filtering options we offer, so you find the toys you want in our vast offering)
The sitemaps also only include the primary image of each product.

Delivery by Exotic Erotics on it’s way

You know the drill…
A new delivery of Dildos by Exotic Erotics (English / German) is on it’s way.

We expect it to arrive in 9-16 business days (including customs).

Then we just have to count, label and sort it for the new stock to be available in our shop (English Shop / German Shop).
When that happens, we’ll report here again.
If you want to track this delivery, you can do so here.
In case you are eagerly awaiting some toy to be in stock again.

Custom Dildos:
For a few days now, it will be possible to order custom variation again. Just contact us via email, stating all the details like colour and firmness. Then we’ll provide you with a custom product that can be ordered exactly 1 time via the regular ordering process. The only  difference is that it obviously takes longer to ship and we require it to be fully paid right away. Also for custom made products there is no 14 day return period.
