The answer is rather poor in my opinion, they boil down to:

This is complicated, I suffered from it, please see my solution in code [link] and my upcoming tutorial [sitelink]

Sometimes the answer is not even ontopic:

Here's rather disproportional users response. My comment was edited to add "and promoting your site":

Now he is deleting his answers I had pointed as off-topic and one with comments quoted above.

• Looks like he just goes through [isometric] tag. – Kromster says support Monica Jan 16 '15 at 13:16
• In general you safely vote to delete link-only answers. Especially if, in situations like this, they are borderline spammy (although you may want to flag the posts for moderator attention in that case as well). – user1430 Jan 16 '15 at 16:47

Flag the answers for moderator attention with a comment, or flag them as spam if they're really bad.

I think if an answer happens to include a link to a tutorial you made, that's OK. However, if you're creating answers to direct users to a tutorial you made, that's promotion and not what this site is for.

I deleted some of the answers and edited others to remove the link to the personal site.

UPDATE

The user in question has now self removed all of their posts.

Firstly, my "site" is only for educational purposes. No commercial purposes. That does not matter?

• Please do not vandalize others answers. I have just reverted an edit you did, replacing other users answer with <deleted><deleted><deleted> – Kromster says support Monica Jan 16 '15 at 14:51
• Who force to remove posts to others is who are vandalizing the platform – celtic.sadness Jan 16 '15 at 14:59
• @celtic.sadness I think you should take some time to read the help center. – user1430 Jan 16 '15 at 16:56
• And no, it doesn't matter if your site not "for commercial purposes." As Byte said, it's fine to include a link to your own site in an answer now and then, but the answer must stand on its own without the link. Copy-pasting the same answer every remotely-related question, and commenting on other questions to direct users to answers you've provided elsewhere, and attempting to vandalize other user's answers on the same question is not appropriate behavior on this site. You may consider this a warning; further misbehavior like this will result in disciplinary action. – user1430 Jan 16 '15 at 17:05
• This is not an answer, it is a comment. – user253751 Jan 23 '15 at 1:19

As a long time I was trying to solve the isometrical sorting problem and then I found the solution. I was feeling to publish for other people "my solution". I repeated a lots the same comment because I was answering to everybody who had the same problem. All the questions was distributed by all the platform. How I could answer only one post for everybody?

• If people are having the exact same problem, you should flag the questions as duplicates of each other - and they will be closed / redirected / merged where appropriate. Copy-pasting the same answer to multiple places is not acceptable here. – Jesse Dorsey Jan 16 '15 at 16:39
