Alex,
Using ahrefs, I am seeing 880 backlinks to the site. Of these, there are a couple of bad ones (the main porn site with keyword anchor text and 99 links). For that one the whois data is all available and he is registered with gDdy, is in San Diego, etc. (Easy way to pressure the take down). The one with bloom in the name is the same way. I did not look at all.
Overall, you have some good links here from other photography sites, etc. I would send a note to the webmasters of these sites and ask them to remove them. If they do not respond in a week, send it again and each time keep track. I would send via email and attach a read receipt. If they don't respond I would report abuse to the registrar gDdy in both cases here.
You are not at a place IMO where you need to use the disavow tool, etc. Write up a template email, put in the 5 to 10 offending sites and send them the email. Keep a log and copies of any and all correspondence with dates, etc.
If you need further direction, we are here,
Robert
