In reply to Rambler's query, Ash tells me that his income is generated by the number of 'hits' on the site which in turn generates a greater number of adverts appearing on the site (but not necessarily viewed by the user, the adverts only need to appear to generate income). The greater the number of adverts that appear, the more money Ash receives.
If a blocker is used, then that 'hit' on the site doesn't count, therefore if everyone used blockers there would be no 'hits' which would mean no income and no site.
The income pays for the staff needed to create and maintain the whole Crossword site, not just the Forum. The regular updates take many hours of work and the staff, who all have university degrees, are obviously paid salaries commensurate with their qualifications.
The videos last week generated a good income but Ash took steps as soon as he could to have them turned off when he realised the problems they were causing. It was unfortunate that it happened over the week-end which delayed their removal but everything should be back to normal now.
I hope this explanation helps everyone understand the situation regarding the adverts and the necessity for putting up with them. If it's any consolation, they annoy me as much as they annoy everyone else!!
