We get a lot of spam answers (and I've just seen a spam edit) with links to domains selling dubious software. There are a few websites that claim to offer tutorials for recovering data from a broken phone, but the "tutorial" is an advert for PC software.
The links are added indiscriminately by newly registered or anonymous users, often to inappropriate questions, and also sometimes to questions where they would be a reasonable answer. The text themselves is often spammy-looking, repeating the same phrasing several times or pasting text from their site, for SEO purposes. Even when the answers are sometimes relevant, I don't think we ought to encourage commercial users to follow this scatter-shot approach and rely on our users spending time deciding which posts might be appropriate.
The websites in question look suspicious because (1) they don't give any contact details or official information on the company selling the software, not even a country of origin; (2) they offer a PC software download for an Android problem; (3) they have heavy use of SEO keywords, often with a separate URL per device; (4) often they hide their WHOIS information to make sure you can't find out who they are. These are not properties of honest software businesses.
Domains I've seen people try to link to include:
- istonsoft.com (hidden whois information)
- swesoft.com (based in CN)
- android-data-recovery-software.com (same owner as swesoft)
- z0download.com (hidden whois information; here's a huge edit that added this link)
- yodot.com (hidden whois information; here's an answer)
- android-mobile-manager.com (hidden whois information)
We have a zillion questions on recovering deleted files, and AFAICT they all attract this kind of spammy answer/edit. Certainly, several have been protected for this reason. I'm proposing to reduce the number of spam answers/edits that get through review, and to reduce the load on reviewers, by stopping our repeat offenders earlier.
